I have three problems with this kernel.

First, there's a mutex lock warning as in the appended trace and my USB
mouse doesn't work.

Second, kpowersave is apparently unable to get the battery status,
although the data in /proc/acpi/battery/BAT0/ seem to be correct
(this also happened with 2.6.17-mm2, but it did not happen with
2.6.17-rc6-mm2).

Finally, I'm still seeing slab corruptions in dmesg (eg. at the end of the
appended trace).

Greetings,
Rafael
