------- Comment #41 from [EMAIL PROTECTED] 2007-11-23 21:05 -------
thanks for the info in comment #34 and comment #35
interrupts.before shows 21 acpi
interrupts.after shows 8780 acpi
What happened between these two snapshots?
And what does "grep HZ .config" show? (will tell us how far apart snapshots
are)
Can you reproduce the issue this way?
cat /proc/interrupts; modprobe thermal; cat /proc/interrupts
Also,
the acpidump output is interesting. Your "after" snapshot
on line 1100 showed that the Global Lock was held.
$ diff acpidump.before acpidump.after
1100c1100

dis-assembled via iasl -d, the FACS looks like this:
[000h 000 4] Signature : "FACS"
[004h 004 4] Length : 00000040
[008h 008 4] Hardware Signature : 0000120F
[00Ch 012 4] Firmware Waking Vector(32) : 00000000
[010h 016 4] Global Lock : 00000002
[014h 020 4] Flags (decoded below) : 00000000
S4BIOS Support Present : 0
[018h 024 8] Firmware Waking Vector(64) : 0000000000000000
[020h 032 1] Version : 00
This is not really a good sign -- as the global lock
should be held for durations so infrequent and so quickly
that it would be very unlikely that you'd catch it with acpidump.
