Summary: Asus P5AB broken BIOS reading ESCD
Kernel Version: 2.6.0-test6
Status: NEW
Severity: normal
Owner: mbligh@xxxxxxxxxxx
Submitter: cesarb@xxxxxxxxxxxxx

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:
