Subject: 2.6.21.3-rt9: SMP errors with VIA Rhine on Uniproc

Hi,

I'm having some trouble with the 2.6.21 -rt series on my single
processor machine:

APIC error on CPU0: 01(01)
 [<a010ce5b>] smp_error_interrupt+0x5b/0x70
 [<a01034f8>] error_interrupt+0x28/0x30
 [<a024ca38>] iowrite16+0x28/0x30
 [<a02c7ecf>] rhine_interrupt+0x6f/0xb20
 [<a039d553>] __sched_text_start+0x303/0x800
 [<a013f37c>] handle_IRQ_event+0x5c/0xe0
 [<a013f8c9>] thread_simple_irq+0x59/0x90
 [<a013febb>] do_irqd+0x25b/0x2e0
 [<a013fc60>] do_irqd+0x0/0x2e0
 [<a012e538>] kthread+0xa8/0xe0
 [<a012e490>] kthread+0x0/0xe0
 [<a010361b>] kernel_thread_helper+0x7/0x1c
 =======================

This looks like it has to do with my onbaord VIA Rhine VT6102 ethernet
controller. After two or three of these errors, the network performance
decreases massively.

On vanilla 2.6.22-rc series I also get a lot of APIC errors, but they
show no trace at all.

The kernel is compiled without SMP support.

Any idea for a fix?

Thanks,
Thomas
