	I had the same symptoms on an uniprocessor IBM PC300GL (pretty standard
pc, 32MB ram, 333MHz celeron [pre-coppermine], 82371AB PIIX E-IDE/ACPI
chips,
Intel Motherboard, 66MHz bus), S3 Trio3D (IBM integrated - **does that
mean anything to you? XFree86-SVGA doesn't work on it, but XFree86-S3
version 4.0.1
-RH 7.0- seems to work fine with the s3virge driver) AGP graphics board
(2MB
vram) plus an Avance ALS4000 card are all I've got. I was worried
because
I don't have any 8259A's on my motherboard and this led me to kgcc.
	The problem occured _only_ when I, unknowingly, used RH 7.0's gcc 2.96
(not one of the updated 2.96's). With that build (a 2.4.8 kernel), I
learnt my lesson when linux got utterly stuck twice in a single day.
Since then, builds with standard gcc's recommended by Linus (egcs/kgcc
&& gcc 2.95.3) have seen the end of this problem. The message came up
during normal use, not in a special situation such as bootup, etc.
	Hope this has been of some help.

PS: Is gcc-2.96.99 currently in RawHide as good (or better ;) as
gcc-2.95.3 for kernel builds? Jakub Jelinek seems to be doing a good job
on it...
