Hello.
I have:
CentOS 5
2.6.18-8.1.10.el5 #1 SMP kernel
AMDx2 3000+ CPU
GIGABYTE GA-M61P-S3 Motherboard
RAM (2x1) 2Gbyte
USB mouse & Keyboard

After some idle time, the keyboard and mouse get deactivated.
The system reports:

localhost kernel: irq 177: nobody cared (try booting with the
"irqpoll" option)
< SNIP >

Any ideas?

Thank you for your time

Hi T. Kontogiannis,

Well one of your drivers seems to be having trouble during idle and causes
a kernel panic, I have seen this happen on some SMP systems before, can you
post the contents of your `/proc/interrupts` file and perhaps also the
output from `lspci -v`.

Cheers,
gamaral
