------- Comment #6 from [EMAIL PROTECTED] 2008-08-22 13:48 -------
It's rather impossible (because of the "throttling" of io, as I wrote already).
I tried to, anyway - but pay attention, that in fact it has been done really
AFTER the problem has been observed, not during - and below is the result of
cat /proc/interrupts :
CPU0
0: 27516 XT-PIC-XT timer
1: 287 XT-PIC-XT i8042
2: 0 XT-PIC-XT cascade
3: 3 XT-PIC-XT ohci1394
4: 1 XT-PIC-XT
6: 5 XT-PIC-XT floppy
9: 0 XT-PIC-XT acpi
10: 17598 XT-PIC-XT sata_sil
11: 728 XT-PIC-XT uhci_hcd:usb1, eth0
12: 8723 XT-PIC-XT i8042
14: 1204 XT-PIC-XT ata_piix

...but, alas, it's not possible to trace anything using "top" ("frozen" output
for duration of the "throttling").
BTW: Did you mention the comments from the mail at the list, sent at Tue, 19
Aug 2008 13:48:07 +0200 by Dan Vratil <[EMAIL PROTECTED]>, with the
subject "ACPI failure"? He wrote: "Then in one version (i think it was
2.6.25.6, but not sure) ACPI tables were updated to be compatible with Windows
Vista, but it has broken down my ACPI".
I think, he just described the same problem.
