> During boot with acpi=off Bad idea, except as a debugging aid.
I completely agree. Without acpi=off, the system does not boot at all, see bug 689420.
> The full dmesg output is attached. The attachment seems to be missing. Please also attach "acpidump" output.
Sorry. Alas, the output of dmesg is not 100% reproducible: on this boot no BUG message occurred. Now I have attached an old log from /var/log/dmesg.2.gz with BUG. I'll try acpidump in the next e-mail.
