Problem Description: Kernel oops when trying to start ACPI - most of the time,
different messages, mainly (from a 2.6.7-mm1 kernel):

Errors seen with kernel 2.6.5-mm6:

ACPI-0183: *** ERROR: Hardware never changed modes
ACPI-0089: *** ERROR: Could not transition to APCI mode

No ACPI aswell with vanilla 2.6.7.

no Problems with kernel 2.6.4-mm1!

Steps to reproduce: Compile kernel with version => 2.6.5 and try to boot with acpi.

/proc/acpi/info from a running 2.4.25-gentoo-r2 kernel:

version:                 20040116
states:                  S0 S1 S3 S4 S5

Any help appreciated...

regards,
 Alex :)

.config from vanilla kernel version 2.6.7
Comment 2 Alexander Weber 2004-07-09 05:45:05 UTC 
after some other test, i found a config that is working on the current knoppix
3.5 dvd.
Comment 3 Len Brown 2004-07-14 13:40:02 UTC 
actually I think this bug is valid.
Looks exactly like the CONFIG_SCHED_SMT failure reported here:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=125841
are you sure this happened as far back as 2.6.5?
I thought it started in 2.6.7

can you diff the working and failing .config?

Diff between 2.6.6 (which workd) and 2.6.7 (not working) configs

I attached a diff between a working kernel version vanilla 2.6.6 (based on a
generic knoppix config, so there are a lot of modules used) and the nonworking
vanilla 2.6.7 (home brew).

As i've seen in the thread mentioned above, it think the CONFIG_SCHED_SMT is
the problem in the 2.6.7 kernel.

I hope i can test the 2.6.7 with the patch in the next days...

The patch from the other page
(https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=101570&action=view) did
the job for me. It work's :-)
Comment 6 Adrian Ulrich 2004-07-31 01:06:05 UTC
