Random IDE Lock ups with via IDE

Random IDE Lock ups with via IDE

[Jim Gifford]

I have been using the 2.6.10.x series kernel for a while on my other 
systems with no issues at all.

But on my laptop which has the via 686 chipset, I started having some 
wierd issues. This happens after about 2 weeks of non-shutting down

Here is a sample of the data from my kernel log

Tested the hard drive it passes. Any other suggestions

Re: Random IDE Lock ups with via IDE

That's not a bad platter issue.  It could be the electronics on the
drive have a problem, but more  likely something happened like the
drive spun down.  If that is the case, the reset at the end should
have woken it up.  Does the drive work correctly after the reset?

Re: Random IDE Lock ups with via IDE

[Jim Gifford]

Ross,
    I thought of that to, I just have 2 laptops that are identical here 
now. I have placed a different drive in the other one. So we can test 
it, but looking through all my logs that I backed up, this problem 
started when I put 2.6.8 on the laptop. I'm wondering if it could be an 
ACPI issue or IDE issue, but have no idea on what to really look for.

Re: Random IDE Lock ups with via IDE

Since you say the problem started with 2.6.8, perhaps the easiest
thing to do is look at the
kernel you say worked and its config and then just diff it vs 2.6.8.

I took a second look at your original message, and since it's an irq
timeout, it could just be that your drive is slow to answer a command
and then is confused by the error recovery code.  Having two identical
laptops makes this easy.  If your other laptop has the same problem,
then it's software (or buggy hardware that the software hasn't figured
out how to work around) if it doesn't, then it's hardware and there
are a couple of things that can be tweaked to see if it fixes things.

Re: Random IDE Lock ups with via IDE

What do you recommend trying?

Re: Random IDE Lock ups with via IDE

[Ross Biro]

If you are using the legacy IDE layer you want to tweak WAIT_CMD.  For
testing, you can make it really large and see if that impacts your
problem.  A drive vendor once told me that it could take more than a
minute for an IDE drive to complete a command.  I no longer purchase
drives from that vendor.

I'm not sure what libata uses, but my guess is it defaults it from the
SCSI layer.

If tweaking these time outs make your problem go away, odds are what
happened was that your drive remapped a few more bad sectors and now
takes a little too long to complete commands.  The linux ide error
recovery code does a WIN_IDLE_IMMEDIATE when there is a problem.  This
is allowed by the ATA-2 spec, but confuses most modern drives.  So
once you start getting errors, often the drive gets so confused, you
never stop.

All vendors could potentially take more than 30 seconds to complete ATA 
commands such as FLUSH CACHE EXT, in extreme cases.
