ide taskfile and cdrom hang

ide taskfile and cdrom hang

[Mark Haverkamp]

[-- Attachment #1: Type: text/plain, Size: 694 bytes --]


We have some test machines here at OSDL that have a problem with the ide
cdrom driver hanging when we cat the /proc/ide/hda/identify file. After
30 seconds the console displays: "hda: lost interrupt" which reoccurs
every 30 seconds forever. We noticed it on 2.6.2-rc2-mm1 but It looks
like this has been a problem for a while. Our test machines just changed
their configuration to use make defconfig.  I found that if
CONFIG_IDE_TASKFILE_IO is N then the hang doesn't occur.  Is this a
common problem or are there just certain drives that won't work with
taskfile i/o enabled?  I've included my .config, lspci as attachments.  
The cdrom model is CD-224E.

I looked at this some time ago together with BenH and Bart. The problem 
seems to be that the taskfile statemachine for identify is quite broken.
(even when it didn't hang it usually returned only garbage on other
CD ROMs). 

The CD ROM doesn't answer the request for some reason and then the
Linux taskfile code goes into an endless loop sending retries.

Bart had a patch to at least cure the hang by erroring out.

Does 'hdparm -I /dev/hda" work?  If so can you try this patch?
It reverts taskfile code to use old (non-taskfile) order of accessing
port registers for ATAPI identify command.  This is a good starting point.

If CONFIG_IDE_TASKFILE_IO is N code just ignores BUSY status of a drive
and reads some random data.  I would like to have this problem solved
at least instead of adding the same workaround to CONFIG_IDE_TASKFILE_IO.

Thanks,

hdparm -I /dev/hda didn't hang.  I got this on the console:

hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hda: drive_cmd: error=0x04Aborted Command

I added the patch that you provided and I still get the hang when I cat
/proc/ide/hda/identify.  I put a printk In the code to make sure that it
was going through the added code, and it is.

That's okay.
hdparm first tries WIN_IDENTIFY which can fail on ATAPI devices.

So it is something different.  Can you give this patch a go?
We will know more about what's going on.

Now, can you comment out "(UDELAY(10))" printk and add printk for "retries"
variable after while {} loop.  I thought there will be more "(UDELAY(10))"
messages - but I forgot about delay introduced by printk() call :-).

I ran twice, got the same results:

1)
hda: (WAIT_NOT_BUSY) status=0x50 retry 94
hda: (CHECK_STATUS) status=0x50
hda: (WAIT_NOT_BUSY) status=0x50 retry 94
hda: (CHECK_STATUS) status=0x50


2)
hda: (WAIT_NOT_BUSY) status=0x50 retry 94
hda: (CHECK_STATUS) status=0x50
hda: (WAIT_NOT_BUSY) status=0x50 retry 94
hda: (CHECK_STATUS) status=0x50

Is this output for single 'cat /proc/ide/hda/identify' run?
There should be only one WAIT_NOT_BUSY and one CHECK_STATUS.

Wow, 94 retries vs. limit of 5 previously.

Please also check if  'hdparm -Istdin</proc/ide/hda/identify'
returns correct information now.

I see two for each cat.  Also, the 94 is the leftover number. So there
were probably about 6 retries.

The 94 is the leftover number. Retry started at 100 and was decremented
in the status check loop. So there were probably about 6 retries.

Yep, I need some caffeine or sleep :-).
Okay, so 6 retries were needed and the limit was 5.
