| I got the following kernel errors hundreds of time, in two different sessions:
| Jun  4 21:51:56 ws1 kernel: do_IRQ: 1.193 No irq handler for vector

| kernel = 2.6.21-1.3194.fc7

| Hardware is dual Opteron 244 CPUs on an MSI K8T Master FAR motherboard, 2GB
| RAM.  Machine works fine on F6 kernels.
| I found references to these log file entries for 2.18 and 2.19 kernels, but
| found nothing for my current kernel...

Are you refering to
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=225399 ?

I experienced that in 2.6.20-1.2944.fc6 (x86_64)
from http://people.redhat.com/cebbert/kernels/
(My messages are #64 and #68).

Now I that I've updated to F7 I have worse problems so I don't know if
I still have this one.
