IDE cdrom problem with PLEXTOR DVDR PX-608AL

IDE cdrom problem with PLEXTOR DVDR PX-608AL

[Hans-Peter Jansen]

Hi, 

I suffer from unreliable cdrom operations (failing DAE and burn sessions) 
with the openSUSE 2.6.18.8-0.7-bigsmp kernel.

Additionally, the syslog is continuesly spammed with:
 
Feb 12 00:03:22 kernel: hdc: cdrom_pc_intr: The drive appears confused (ireason = 0x01).
 Trying to recover by ending request.
Feb 12 00:57:52 kernel: hdc: cdrom_pc_intr: The drive appears confused (ireason = 0x01).
 Trying to recover by ending request.
Feb 12 01:36:21 kernel: hdc: cdrom_pc_intr: The drive appears confused (ireason = 0x01).
 Trying to recover by ending request.
Feb 12 01:38:49 kernel: hde: cdrom_pc_intr: The drive appears confused (ireason = 0x01).
 Trying to recover by ending request.
Feb 12 08:06:07 kernel: hde: cdrom_pc_intr: The drive appears confused (ireason = 0x01).
 Trying to recover by ending request.

I drove that devices on a pdc20268 based Promise Ultra TX/2 100 card for 
some time, which had some IDE/ATAPI issues documented. After exchanging 
that PCI card with a "Silicon Image PCI0680 based one, the problem persists.

Is there any firmware/atapi protocol problem known with these drives?

Hi,

can please you test this with a more recent kernel. Yours is almost ancient -
from Sep. 2006.

Thanks.

Sure, sorry. Here we go:

 Trying to recover by ending request.
Feb 14 00:27:27 kernel: hdc: cdrom_pc_intr: The drive appears confused (ireason = 0x01).

Actually the interrupt handler in ide-cd got rewritten and you're still using the
old one (cdrom_pc_intr vs cdrom_newpc_intr). Those changes went into mainline before
the 2.6.25-rc1 so we'll be able to test the new one only when you try out 2.6.25-rc1
or wait until 2.6.25 is released in case you don't want to try hazardous materials
such as an -rc kernel[*] :).

Bart?

*. As a matter of fact it runs quite smoothly on my machines.

Hrm, I highly depend on that system being reliable¹, thus I would prefer a 
diff, if feasible at all. That way, any breakage may be embanked to PATA.

OTOH, I'm willing to help to get down to the issue (knowing that this is the 
only way to finally get rid of it).

Thanks,
Pete

¹) As a matter of fact, I suffered from way to many regressions in essential
   subsystems (kernel, X, nss_ldap) lately, not to speak from the usual
   calamities in peripheral areas of such complex beasts.

2.6.25-rc1-git1 if you are using IDE.

however it may still have this problem

	if (ireason == 0) {
		write = 1;
		xferfunc = HWIF(drive)->atapi_output_bytes;
	} else if (ireason == 2 || (ireason == 1 &&
		   (blk_fs_request(rq) || blk_pc_request(rq)))) {

we problably need to call ide_cd_check_ireason() also for REQ_TYPE_ATA_PC
requests and remove (blk_fs_request(rq) || blk_pc_request(rq) here

		write = 0;
		xferfunc = HWIF(drive)->atapi_input_bytes;
	} else {
		printk(KERN_ERR "%s: %s: The drive "
				"appears confused (ireason = 0x%02x). "
				"Trying to recover by ending request.\n",
				drive->name, __FUNCTION__, ireason);
		goto end_request;
	}

Hans-Peter,

i will prepare a patch against 2.6.24 for you to try later.

Hi,

i thought that backporting ide-cd to 2.6.24 would be self-contained but the
problem is that it pulls in changes made in the block layer (ll_rw_blk.c splitup)
and if i pull those also in the patch, i can't guarantee the stability of your
system. Besides, this turns pretty fast into a chained pulling which will result
into a subset of 2.6.25-rc1 applied ontop of your 2.6.24.1 kernel so the only
alternative is to wait after 2.6.25 has been released and tackle the problem then.

well the driver probes the bios for that data and assigns the irq line it gets
from it.

since your cdrom seems to be hda from what i've seen above, try booting with
'hda=noprobe' or maybe 'hda=none' to see which one turns the probing off for
you. See Documentation/ide.txt for details.

Roughly speaking, cdrom.c is the unified cdrom layer that delivers common
functionality to all the cdrom devices. ide-cd and others are the low-level
device drivers that offer drive-specific functionality only. In case you wanna
know more about it, see Documentation/cdrom/cdrom-standard.tex (might want to
convert it to something more readable) and read the section on stackable kernel
modules in Linux Device Drivers, 3 ed.

Does the following patch help?

[ It makes ireason handling for REQ_TYPE_ATA_PC requests be the same as
  for other request types so "ireason == 1" quirk is used if needed. ]

Oh.  I thought from all the 'IRQ routing/balancing' and the like in the
kernel there might be a way to switch things around, give the
Realtek driver a different IRQ than the one being used by the ide driver.
Just my crossed-fingers hope.

It's attached as file 'dmesg.bug.out'.

I tried both options, but in both cases there was no difference; the ide_cd_mod
module was still loaded and the 'confused' message still popped up.

I did four boots/tests of the 2.6.25-rc2 kernel, with and without those
boot parameters ... on all four I had the 'confused' message several times:

hda: cdrom_newpc_intr: The drive appears confused (ireason = 0x01).
Trying to recover by ending request.

but in one - the boot with hda=noprobe - I got pages of these
error messages right after:

hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hda: DMA disabled
hda: ATAPI reset complete
hda: cdrom_decode_status: status=0xc0 { Busy }
ide: failed opcode was: unknown
hda: ide_intr: huh? expected NULL handler on exit
hda: ATAPI reset complete
...

and the system essentially hung.  I don't know if that was due to the
'hda=noprobe' or if that extra sensitivity is seen only every now and then.

I tried to apply the patch but failed; I probably did something wrong.
I deleted everything in your message above 'Index: b/drivers/ide/ide-cd.c'
and ran 'patch --dry-run -b -p1 < ../bart_patch'.  This is part of my script
log:

Sorry.  Can you tell me what I did wrong?

Well, this sounds strange. Are you sure you're entering the boot options
correctly on the kernel command line? Which is your boot loader? I just booted
my machine with 'hdc=noprobe'  (hdc is my cdrom drive) and here's what i get:

so it seems you should check whether your kernel is receiving the 'hda=noprobe'
boot option at all, or something along that path is going wrong...

are you sure you're _really_ using 2.6.25-rc2? Applying the patch against that
kernel works just fine, no fuzziness or even rejects. Care to try out on a fresh
kernel source tarball? After all, building a kernel with your quad core cpu won't
take that long :-) when using make -j8 or something in that order.

I'm entering the option 'hda=noprobe' (as one example) right after my boot
label in LILO.  The dmesg output I attached last time was a boot of straight
2.6.25-rc2 without any options; I've attached 'dmesg.noprobe.out' which is
the result of a boot with 'hda=noprobe'.

I must have done something stupid, but I can't see what; if you look at this
line from the dmesg output:

Kernel command line: BOOT_IMAGE=linux_2.6.25rc2 ro root=900
md=0,/dev/sda5,/dev/sdb5 hda=noprobe

... it would suggest the option 'hda=noprobe' was entered correctly?

Heh.  This is my first new machine in 8 years, and I couldn't wait to start
using multiple cores.  I was quick to discover the '-j' option ... but I only
do '-j 4'.  Anyway ... I'd downloaded the full baseline linux-2.6.24.tar.bz2,
unpacked it, and then ran the patch patch-2.6.25-rc2.bz2 against it.  That
patch ran perfectly.  And I was in the right directory when I ran Bart's patch,
as I listed in my earlier e-mail!  All indications were that I was running the
2.6.25-rc2 kernel as required, I thought.

Well, I see that rc3 is out; maybe I'll give that a shot.

ok, let's try something else: change the line "#if 0" to "#if 1" at the
beginning of kernel/params.c, it looks like:

#if 0
#define DEBUGP printk
#else
#define DEBUGP(fmt, a...)
#endif

rebuild your kernel, and reboot with it. Then, please send me that boot log to
see whether the kernel command line is being received from the boot loader and
what exactly is getting parsed. Thanks.

Please see whether you can apply the patch Bart just sent and if that still gets
mangled and cannot be applied, consider making those changes to ide-cd.c by hand
- after all, there are only several lines that need to be changed so it won't
take that long.

Thanks.

Boris,  I've done that; the output is in attached file dmesg.debug.out.

It looks to me that the kernel still found the IDE DVD drive (hda) ...
in addition
to the system messages when the system was up I found the ide_cd_mod
module loaded on top of 'cdrom' as normal.

Bart, I was able to apply that patch file you attached with no problems, and the
behaviour of the patched kernel changed as follows:

- no more 'confused' messages, nor the rush of other critical messages
that accompanied a system hang on one out of four tests yesterday.

- However, a new message that popped up twice; once after a few seconds
of network activity, and then about 15-20 seconds afterwards:

hda: ide_cd_check_ireason: wrong transfer direction!
hda: ide_cd_check_ireason: wrong transfer direction!

- also, I'm pretty sure that performance of both network and DVD drive suffered.

As to the last ... my new PC, on which I'm doing all this testing, has a gigabit
Realtek NIC.  It's hooked up via null UTP cable to my older machine which has
a 100Mb/s card.  ethtool shows that they both auto-negotiate to run at 100Mb/s
full duplex.  When I run my network test (pumping through /dev/zero across ssh
from the old machine to the new) the network stats tell me that I'm getting
10MB/s out of the link, which is what I would expect.

With the patched 2.6.25-rc2 kernel running with no activity reading the DVD
but the network going flat out (on the old PC's end) I noted that I was only
getting only 8.0 or 8.1 MB/sec, rather than the 10 MB/sec I've seen in the other
tests..  There was no other network traffic or cpu load on the machine(s).

Then, when I mounted a DVD disc and did a 'wc /mnt/*' of its contents
an iostat showed me that I was getting only about 6MB/sec out of the DVD
drive, which is less than I'd expect.  As soon as I killed the network send
iostat's report zoomed up to roughly 10MB/sec.  So it seemed to me that,
in addition to the 'wrong direction' messages, I was losing some performance
on both the NIC and the DVD drive.

Regards to you both,


Brad

it seems that your boot loader is not supplying the kernel with the boot params
properly as can be seen from the excerpt below:

...
Kernel command line: BOOT_IMAGE=linux_2.6.25rc2 ro root=900 md=0,/dev/sda5,/dev/sdb5 hda=noprobe

and, as a result, the probing of hda still takes place.

Bart, can we assume here that some of the nic interrupts somehow get handled by
ide-cd or something gets mixed up there?

I'm aware of one potential deficiency with shared PCI IRQs:

disable_irq()+enable_irq() usage in ide_do_request() (can be fixed by not
starting the new request from ide_intr() and instead waiting for block layer
to do it) but it doesn't seem to be related...

Besides ide-cd shouldn't get the control if the device is still BUSY...

[ I find it weird that all previous error messages contained ireason == 0x01
  while "wrong transfer direction" is triggered by ireason == 0x00/0x02 ? ]

Is there any background process polling DVD drive?  haldeamon?

If so please stop it and see if it helps.

Thanks for testing it.  I merged the patch since it is an improvement over the
old behavior and it is easier to look for full fix with it applied.

Same command works just fine for me with 2.6.25-rc2/3.

It could be that the patch got damaged somewhere on the way
(to eleminate this possibility I'm attaching it to this mail).

Thanks,
