I was getting this problem, and advice from smartmontools people was 
to clean out the box and reseat all cables etc.  Seemed to work for 
me on the box at work with this DMA timeout issue - BTW, always 
happened at idle, like 2:15am in the middle of the night etc.

Thks, folks, I wouldn't really suspect of bad cables/PSU, this was an
eye-opener. I have just opened the box and reseated the 80-wire IDE
cable to my hda device, and I will consider replacing it, just in case.
The PSU is brand new, 450W -- although it could be bad quality, I will
try to check this out.

BTW: Nick, I missed your msg because you didn't cc me. My hda also
usually gets disconnected at early hours in the morning, as you pointed
out. I arrived today to work and it had happened again =/ Last entry
on/var/log/messages was around 1:30am, and it was about a NFS mount that
had expired.

Best,

Andre

Hi Andre,

Sorry, I too am not subscribed to the list, and I read (and reply to) 
from:

http://marc.theaimsgroup.com/?l=linux-kernel

I totally overlooked CC'ing you.

Anyway, new IDE cable did fix the box at work for me.  Also I only 
used smartd AFTER the problem arose, not before, so it was not smartd 
that caused it.

Regards,

Nick

No worries. I have to remind myself over and over again to put the
"please cc me" header on every msg =)

Thks, this is definitely valuable info. I will surely go after some new
cables to see if it improves my situation (I hope it does, otherwise I
will have to move services away from this box and relocate them to other
servers, which will be a PITA...)

On a side note, I browsed 2.4.27rc2 changelogs today, and there is some
interesting stuff there about interruptions, ACPI etc. Looking forward
to trying it out.

Thks again,

Andre

2.4.26: IDE drives become unavailable randomly

[Andre Costa]

(please cc me on any replies, because I am not subscribed to this list;
if I do need to subscribe, just let me know)

Hi,

I am using 2.4.26 SMP on a ABIT AT7 mobo, with a 2.8GHz P4 processor
with hyper-threading enabled. I have one 80GB Seagate IDE disk
as /dev/hda, and from time to time it seems to "disappear", usually
after these messages appear a couple of trimes on/var/log/messages:

Jun 27 17:15:00 dali kernel: hda: status timeout: status=0x80 { Busy }
Jun 27 17:15:00 dali kernel: 
Jun 27 17:15:00 dali kernel: hda: drive not ready for command
Jun 27 17:15:03 dali kernel: ide0: reset: success

I already had some ide-related issues, namely the one mentioned here:

http://www.x86-64.org/lists/discuss/msg04679.html

Due to that, I am booting with:

hdc=ide-scsi apm=off acpi=ht noapic

Turning off APIC and keeping ACPI to a minimum seems to have fixed the
"dma status == 0x24" problem, but I still experience the "status
timeout" above, which is very frustrating because this is supposed to be
a server for our intranet.

I tried turning off APM for this disk with 'hdparm -B255 /dev/hda', but
it didn't work:

hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hda: drive_cmd: error=0x04 { DriveStatusError }

I have turned off spindown with 'hdparm -S0 /dev/hda', but frankly I am
not sure this will help (besides being bad for harddisk lifetime).

So, given this scenario, I would really appreciate any suggestions on
how to workaround this issue... Please, let me know if you need
additional info. I am attaching below the output of 'hdparm -I /dev/hda'
in case it helps. I am running Fedora Core 1.

TIA

Andre

I get a similar problem on my Presario laptop.  In my case "all of a
suddend" hda3 becomes write-only.  Next time it happens I'll see if I
can capture a dmesg log or something.  It only seems to happen when I
enable my wifi and do a lot of disk activity [but only once in a
while].  Could be that my wifi and IDE0 share an IRQ?

Of course I'm more apt to blame my laptop than Linux since the same
kernel [well diff build options but you know what I mean] works just
fine on my two desktops in the house...

I can't say the situation is the same here -- actually, it seems to be
more related (in my case) to idle times: usually this happens when the
system is under light load (or under no load at all), like between
0:00am and 6:00am. This is why my primary suspect is APM (I could be
completely wrong, of course). Also, I don't have wifi.

Yeah, I know what you mean: the same Linux distro has been running
flawlessly on other boxes around here for months (with different
hardware specs, though). Mine OTOH has a sad uptime record of 5 days...
=(

I agree Linux works (actually, it rocks =)), been using it for years
both at home and at work, but sometimes a specific hardware combination
(or buggy hardware/BIOS/firmware etc.) pushes it to the edge, reaching
some weak spots that need to be "hardened". Some hardware simply doesn't
work at all (I hope that's not my case...)

Best,

Andre
