Summary: Asus P5AB broken BIOS reading ESCD
Kernel Version: 2.6.0-test6
Status: NEW
Severity: normal
Owner: [email protected]
Submitter: [email protected]
Distribution: Debian testing/unstable
Hardware Environment: Asus P5AB
Software Environment:
Problem Description:
Trying to read /proc/bus/pnp/escd causes an oops. Looks like the PnPBIOS is
broken. However, it's not exploding_pnp_bios, since only reading the escd causes
it (the boot probe works fine).
I think a new function should be added to the DMI blacklist to block trying to
read the ESCD.
Steps to reproduce:
cat /proc/bus/pnp/escd
Oops output:
Sep 28 23:57:00 seed kernel: PnPBIOS: get_stat_res: use ESCD instead

Well, I do have a SoundBlaster AWE ISA on that board, and it didn't
break the floppy.
I have downloaded the latest BIOS and will test it later (I don't have
the latest one, the latest one is from 2002 and the one in the box is
from '98)

FWIW: I used to have a similar board (Asus P5A, it actually died a week
ago, so I can't check anything anymore). Never tried 2.6 on it, but I
know it had a flakey PnPBIOS implementation: if you put in a Sound
Blaster AWE64 Gold, you couldn't use the floppy drive anymore. The
latest "Y2K compliant" BIOS (revision 1.005 IIRC) fixed that, it might
also fix this particular bug.

The latest BIOS (a beta one) still has the same problem. Also, it breaks
the main timer (for instance, vmstat 1 takes 2-3 seconds between lines,
and the kernel complains about a broken TSC on boot).

As far as I remember I didn't try the beta BIOS, the latest stable one
fixed my problems with the Sound Blaster and the floppy drive. I only
used the board with 2.4 (last kernel I ran was 2.4.20-rmap15i) and that
worked OK. If that still doesn't solve your problem, I agree the BIOS
has to be blacklisted so we can work around it.
