DSDT table
Not sure if this is useful to anyone, but I went to all the effort of creating it, so I thought I'd share :)
I've attached the DSDT table in some arbitrary disassembled format in case that's useful.

Does this still exist in 2.6.22-rc7? It seems not, although I've only tested it once. I think it's reasonable to close this bug and I'll reopen it if the problem reoccurs. |
Most recent kernel where this bug did not occur: None, it's happened for a long time but ATI have just broken their closed-source driver, now that I'm using the open one, I can report bugs again :) Distribution: Debian unstable Hardware Environment: Novatech Notebook (part of dmidecode is pasted later) Software Environment: Problem Description: ACPI exception followed by oops Sometimes (always?) when my battery runs low, there is an ACPI exception in the logs. Once, there was a coincidental oops in the acpi subsystem. I presume this is some misfeature of my BIOS' ACPI tables? This has happened on this machine with lots of kernels. I could upgrade to the latest kernel, but it will cause me a big headache with my rt2x00 wireless drivers, so I'll only do it if someone thinks it will be useful. Steps to reproduce: Simply wait for the battery to run out...
