Subjectunexpected IRQ trap at vector a0
Dear developers and bug-finders,

I've got a new desktop - some kind of Pentium IV with hyper-threading,
so immediately decided to switch it to 2.6.0-test2-bk8 kernel which was
running on my desktop/laptops for quite a while, but I've got next
problem: when it boots I begin getting my console as well as
syslog/messages flooded with

unexpected IRQ trap at vector a0

(actually first it hanged with PNPBIOS problem - I turned it off)

I modified kernel a bit to don't get all my dmesg filled with only
this error message, so now it is reported only on 1st occurrence (as
well as next string Yarik: APIC is On).

So this error fires up for the first time in the context:

i2c-piix4 version 2.7.0 (20021208)
Advanced Linux Sound Architecture Driver Version 0.9.6 (Mon Jul 28
11:08:42 2003 UTC).
request_module: failed /sbin/modprobe -- snd-card-0. error = -16
specify port
specify port
PCI: Setting latency timer of device 0000:00:1f.5 to 64
unexpected IRQ trap at vector a0
intel8x0: clocking to 48000
ALSA device list:
#0: Intel ICH5 at 0xfebff800, irq 17

And later I'm getting also
IPv6 over IPv4 tunneling driver
irq 9: nobody cared!

Disabling IRQ #9

My logs and kernel configuration (it was patched by
sched-2.6.0-test1-G7, though error existed in pure vanilla kernel as
well - I just already had compiled patched version in my hands already
so decided to proceed with it)

I will provide any additional necessary information.

Thank you in advance for your help
