Re: 2.6.2-rc2-bk1 oopses on boot (ACPI patch)

[Len Brown]

Alessandro,
Looks like you've identifed a regression, probably in ACPI.

Please test the 1st patch attached to this bug report
http://bugzilla.kernel.org/show_bug.cgi?id=1766

If it doesn't address the problem, please file an additional bug report
per below.

thanks,
-Len

ps.
The divide-by zero symptom should be addressed by Dominik's update, now
in the ACPI tree and thus the next -mm patch.

pps.
How to file a bug against ACPI:

http://bugzilla.kernel.org/ Category: Power Management, Component: ACPI

Please attach dmesg -s40000 output (or serial console log if dmesg
unavailable)

Please attach the output from acpidmp, available in /usr/sbin/, or in
pmtools:
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/
