Subject: [PATCH] ACPI oops with 2.5.8-pre3 on asus dual athlon (A7M266-D)
Date: Thu, 11 Apr 2002 00:47:09 +1000 [thread overview]
Message-ID: <20020410144709.GA852@orthos.rcpt.to> (raw)
[-- Attachment #1: Type: text/plain, Size: 234 bytes --]
Null pointer dereference in some deep internal ACPI state thing.
Attached patch gets it past that point, but kernel then hangs after
probing disks (as did -pre2, and possibly earlier ones). Almost
certainly not the right fix :)
