how to diagnose/fix : cannot boot without acpi=off

[Philippe De Muyter]

Hello acpi experts

I have just installed opensuse 11.3 milestone 4 (2.6.33-6-desktop) on a laptop
hp pavilion dv6-1300sb, and it refuses to boot without acpi=off which in turn
prevents me to use the wireless chip.

I would like to diagnose precisely what the problem(s) is/are.

which option should I add to the linux commandline to make it point to the
problem ?  I have already tried 'ignore_loglevel debug' but the last
message is never the same.

Did previous versions of Linux boot properly on this machine?

Please open a bug report:

https://bugzilla.kernel.org/enter_bug.cgi?product=ACPI

and attach the output from acpidump and dmesg -s64000
from your acpi=off boot.

If you can take a photo of the failed boot, or otherwise
describe it in more detail, that would be helpful.

See if any of these random options help it boot:
acpi=ht (likely this will work)
acpi=rsdt
acpi=noirq
pci=noacpi

thanks,

The opensuse 11.3 milestone 4 installation kernel works flawlessly.
The opensuse 11.3 milestone 4 installed kernel does not boot without acpi=off
and often (but not always) crashes at boot even with acpi=off

acpidump : done
dmesg -s64000 : will do when back at home

I have attached several netconsole ignore_loglevel logs to the bug report
