Hi, linux-ide:
We have a workstation with a dual-core Pentium 4 3.4 Ghz processor that
started to panic last Friday. The machine stays up for 15 minutes to
a few hours, then it panics again. We suspect a hardware problem, but
I'd like to ask here whether there's newer libata or other code that
fixes the panic.
I've seen two panics since I heard about the problem and the stack trace
each time has been:
Badness in i8042_panic_blink at drivers/input/serio/i8042.c:988

(Anything confusing about the stack might be due to the fact that I
wrote it down by hand.)
The kernel came with RedHat EL 4.0. Uname -r shows 2.6.9-5.ELsmp.
In case it's useful, here is output from dmesg.

Is this something that's been patched already? An irredeemable hardware
problem? Something else altogether?
If anyone would like more information, I'd be happy to provide it.
Regards,
Nick
