Subject: Dual PPro timer stopping problem


Hi,

I'm seeing a problem that's causing me someone may be able to shed some light
on.

I've been running late 2.5.x kernels on a dual PPro box here for testing
things. After a while (which can be anything from a few minutes to a couple of
days), the timer interrupts stop happening. Most other interrupt sources (such
as the network card, but not, apparently, the keyboard) continue to happen
though. I've tried changing the motherboard and CPU set, but to no avail.

Anyone any suggestions as to what it might be, or what I might try to better
determine the root of the problem?

I've attached the config I've been using for the kernels.

Cheers,
David

Does this happen with "noapic" ?

Interesting:

[[email protected] root]# cat /proc/interrupts
CPU0 CPU1
0: 150710 0 XT-PIC timer
1: 15 0 XT-PIC i8042
2: 0 0 XT-PIC cascade
11: 457 0 XT-PIC eth0
14: 74220 0 XT-PIC ide0
NMI: 35480 150619
LOC: 150451 150454
ERR: 0
MIS: 0

Lots of zeros in the CPU1 column.

It's still going though.

The keyboard is, or at least depends on polling which is
controled by a timer, thus, no timer, => no keyboard.

Eh? Sure, by a timer internal to the keyboard itself. At least x86
hardware has an interrupt wired to its keyboard controller that is used
to signal when a keystroke is available, and if you look into the driver,
you'd see that no timers are used at all.
