This looks like a nasty case where some executable code in the table is
attempting to access a SystemMemory operation region before any OpRegion
handlers are initialized.

We certainly want to see the output of acpidump to attempt to diagnose
and/or reproduce the problem.

Sorry for double post.

With this mail I hand over the acpidump output with the pmtools
Andrew pointed me to.

And a dmesg output with CONFIG_KALLSYMS=y.


I attached them in bz2 format, because of the length.

I hope we find the problem.

Best regards
          Michael

Michael, I'm assuming that a) this problem remains in those -mm kernels
which include git-acpi.patch and that b) the problems are not present in
2.6.13-rc5 or 2.6.13-rc6, yes?

So I think we have a bug in git-acpi.patch?

If that's all correct then can you please test the next -mm (which will
include git-acpi.patch - the most recent -mm did not) and if the bug's
still there can you raise a bugzilla.kernel.org entry for it?

We seem to have a handful of bug reports against the -mm acpi patch.

Thanks.

a.) I don't have any problems in 2.6.13-rc5-git[1-3] and 2.6.13-rc4-mm1 
they are working quite fantastic.
Good work :-)

I reverted them and left them in..no problems with kernels I said above.
Again good work :-)

I would, but the motherboard is dropped from my hardware test approval. 
Maybe I can get it back to test again
if it helps to solve some acpi issues.

Well, I noticed that there are a lots of bugs and I'm willing to find 
search and reproduce them.

I have to say thanks for the great help/feedback.
