Stephen,

Since it seems to be IRQ-related, are there any devices you can remove from the system and/or add back in one by one until the system detects it/them and puts them in their proper place?  Also what do you have in /proc - look there for more clues.

Thanks,
Marc

PC hung frequently while running Firefox and "yum update" on console.
Therefore I started runlevel 3 (init3, textmode) discovering the cause
as follow;

# yum update
.....

<c6405042> do_IRQ+0x70/0x80
......

PC hung here.

I tried several times encountering the same problem. Having checked
BIOS pages and can't find any change there.

Please help. TIA
