No, actually, it's a gcc bug. The C3 doesn't support the CMOV instruction,
which is ok according to Intel documentation, and software should check
whether this instruction is available. gcc implicitly expects every 686 to
have this instruction.
To add up to the confusion, on later VIA CPUs (those with a C5P core and
later), you'll actually want to use 686 to initialize the SSE pipeline,
which is necessary to make use of the xcrypt instructions (which will
otherwise be invalid opcodes).
So is there a way to work around the bug?? Running the i586 kernel does not
make the errors go away. The thing I do not understand is, why sometimes the
kernel panics and other times the machine comes up and plays after spending
several minutes spewing errors.
dmesg output is available here: http://www.tntechs.com/tntechs/hepa-dmesg.txt
if anyone is interested in looking at it.
