Hello,

I'm getting some Oopses with kernel 2.6.5 when there is high load on 
both channels of a Promise PDC20262 (Ultra66) card on a SMP machine 
(Tyan S1834, Via Apollo Pro chipset).

There are no problems when I use 2.6.1, but I have this problem
since 2.6.2.
It only occurs when I use the PDC20262, not when using the onboard
IDE-controller.

It is reproduceable after a few seconds when I use 'dd if=/dev/hde 
of=/dev/hdh bs=512'.
Using of=/dev/null also works, but it takes longer.

Mostly it reports smp_apic_timer_interrupt+1c/140, but the last time
I tried it, it also reports <__mask_IO_APIC_irq+40/e0>.

I've attached the logs and the ksymoops trace.

Regards,
Sebastian
