Hello,

I've got a problem while using Hyper-Threading on a motherboard with Via P4M266A
chipset with 2.4.23 kernel.
Without SMP enabled, I've got no problem with this chip, but when I enable SMP, the
clock runs twice the speed, and interrupts are handled by both virtual CPUs, instead of
the first one, like on other servers I run.
I haven't got this problem with other chips but with this Via chip. There is no special thing
in dmesg.
Have you an idea from what the problem comes? I haven't found any patch for this type
of problem.

Thanks
Miro

hmm, you could try 

 # echo "1" >/proc/irq/0/smp_affinity

which should stop the second 'cpu' from
handling the timer interrupts ...

but this doesn't explain the 2x clock,
which probably is some bug ...

HTH,
Herbert

Thanks but already done. It must be a bug in 2.4.23, because with 2.6.0-test11,
I don't have any problem...

How may one find this bug?

Thanks.

Could you try to narrow down when the problem first appeared? Was it not
seen in 2.4.23-pre3 but showed up in 2.4.23-rc1? The narrower the
better. 

thanks

Hello,

I had the problem with 2.4.22, 2.4.22-ac4, 2.4.23 and 2.4.24-pre1.
The problem is that all the kernel is working "twice the speed".
The command "while true; do date; sleep 1; done;" shows that the date is growing
2 seconds per second... :/
I found a patch for irqbalance for 2.4.23, and now I don't have the problem 
anymore with the clock.
http://www.hardrock.org/kernel/2.4.23/irqbalance-2.4.23-jb.patch

With 2.6.0-test11, I didn't have any problem, but we can't switch to 2.6.0 yet
production.
I think it is a bug with the via chipset, but I'm not able to get deeper in the
kernel code.

Thanks
Miro

Ok, so its been around awhile. Do you remember what was the last 2.4
kernel where you did not see this problem?

Hmm. Just skimming that patch, I notice it won't work on clustered apic
systems. They've dropped the following chunk from set_ioapic_affinity
and forgot to re-add it.

-	/* pick a single cpu for clustered xapics */
-	if(clustered_apic_mode == CLUSTERED_APIC_XAPIC){
-		int cpu = ffs(mask)-1;
-		mask = cpu_to_physical_apicid(cpu);
-	}

Further I can't see how it fixes the problem, but it may just be working
around the issue. I'd be interested in what the patch author thinks.

Could be, but I suspect interrupt routing isn't happening properly at
boot time. The irqbalance code just forces it to be readjusted correctly
once your up and running.

In fact, it is a new motherboard we're testing, and with the oldest version of
the kernel I have, 2.4.18, I have also the problem.

With SMP disabled, I have no problem with any kernel. So it must be in the APIC
init, I think.
I don't know how the patch works around this problem, but it's a workaround. I
can test other kernels to find a "better" patch to find and fix this problem,
and have a stable 2.4.24 that works with this hardware.
If you can suggest other things to test or to identify the problem, I can do it.

Thanks
Miro

Does booting w/ "noapic" help?

Hello,

> Does booting w/ "noapic" help?
No, I still have the time that is going twice the speed.
I included /proc/interrupts, dmesg and lspci. It's with the 2.4.23 kernel without the irq_balance patch.
Hope this help.

Thanks.

John meant 'noapic' not 'noacpi', you'll note that the interrupt
controller types after boot will be XT-PIC instead of say IO-APIC-edge
etc..

My fault...
It works now.
`while true; do date; sleep 1; done` counts well now.
Thanks.
But now, how may I help to find this bug in apic code?
