Today I decided to try the latest revision from Linus' tree (0eddb519b9127c73d53db4bf3ec1d45b13f844d1), to test the latest nouveau patches, but I got stuck while booting the kernel.
You can check the acpi call trace at the attached photo.
After doing bisect I ended up at patch dadf28a10c3eb29421837a2e413ab869ebd9e168, created to fix the bug #14667.
My machine is a MacBook Pro 5,1.
After reverting this patch I was able to boot and test the latest kernel available from Linus' tree.
Please let me know if you need further information to be able to debug this bug.

Please go back to the original kernel (ie. with the commit applied) and revert
only the changes in that commit affecting drivers/acpi/ec.c . Please report
back whether or not that helps.

Read all bits
Please check if this patch helps.
Just tried the patch from comment #5 and still didn't work.
However, I was able to boot fine after removing just the changes from dadf28a10c3eb29421837a2e413ab869ebd9e168 to file drivers/acpi/acpica/exprep.c.

This patch fix the problem.
Just tested and was able to boot without any problem.
Thanks for the fix.

My FSC Amilo fails to boot 2.6.34-rc4 with a repeatable oops that looks pretty much identical to the one shown here. Alexey's "Limit burst to 64 bit" patch solves the problem on that machine.
