RE: ACPI problems with Compaq Evo N610c

I got interested in this recently because I inherited one of these
laptops from work.

I just updated to F.15, and it does indeed fix the windows bit in the
output of 'acpidump -d'. However, even with Tony's recommendation of
removing the acquire/release of _GL in methods C12C and C12D, I still
can't get xbatt or wmbattery to run, even with the very latest -current
(which has had at least one acpi stack upgrade since 7/30). When I run
either command, it locks the box tight. If I ever get a cursor back, I
have to Ctrl-Alt-Backspace to get out of X, since I can't actually type
anything.

I have a feeling that my acpi table didn't actually get overridden
though, due to the following from dmesg:

ACPI: DSDT was overridden.
        -0424: *** Error: UtAllocate: Could not allocate size 6e49202a
    ACPI-0428: *** Error: Could not allocate table memory for [/*
 ] length 6e49202a
    ACPI-0368: *** Error: Could not copy override ACPI table,
AE_NO_MEMORY

Also, the "before" and "after" acpidump's don't show anything different.
So, I'm curious if wmbatt is still working for Tony and Robert or not
with the latest -current.

The other problem I'm having is that doing 'sysctl -a', or just 'sysctl
hw.acpi' locks the system tight for a couple minutes, and never
completes. The last line that's printed to the screen is:

hw.acpi.thermal.tz1._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1

Any ideas on that one?

Thanks,

Doug
