RE: [ACPI][2.6.8-rc2-bk #] - ACPI shutdown problems on IBM Thinkpads (T42)

[Brown, Len]

Oh yes, I have a vivid memory of the T42 in Ottawa not powering down
last week,
even with the lastest ACPI patch.

thanks,

I'll keep looking for patches as you get time.

I appreciate your help.

Disable APIC support and shutdown will work.

Meanwhile, has anyone solved the problem with the Thinkpad-keys after
a suspend/resume?  Volume keys still work, as does the brightness keys,
but Fn+F4 for suspend doesn't (manual suspend still works), and tpb
doesn't see any of the Thinkpad specific keypresses any longer
("Access IBM", Fn+Fx, etc), not even if I restart tpb, and
/proc/interrupts:acpi indicates that interrups are not working for ACPI
any longer.  All other interrupts seem to function properly, and I have
both patches from [1] applied.

The latest (acpi-20040715) ACPI patch against 2.6.7/2.6.8-rc2 works on
my T40 to bring back ACPI  interrupts after suspend/resume.  I don't
know if these will apply to the bk tree or not.  It also makes it so
other buttons besides the power button can wake up the machine (like the
Fn button).

[Shawn Starr]

The buttons sort of work. The video however, does not turn on with X loaded
or without. I get a blank screen. You can tell the machine is powered back
on because you can log into it still (and run find command to see hard disk
activity).

Something else I noticed, when ACPI fails to shut the machine down fully,
and I hold the power button to shut it off completely, I hear a buzzing
sound from the back, if I remove the battery and plug it back in the laptop
becomes completely silent. I'm not sure what this is though (?).

That issue I don't think is connected to ACPI.

Thanks!  This indeed works.  However, Fn+F4 to suspend doesn't work now
(despite generating the proper interrupt), but that might be a
misconfiguration on my behalf.
