Sure, and it only got added to 2.6.19 anyway (however GCC 3.4.6 really does seem to have no problem with it). > But if you can use that machine without the wireless too, it > might be good to try without either. Required, plus I've been running prism54 on three different machines with a huge number of compilers since the early 2.6 days with no problems. > (The rest of your module list looked bog-standard, so if it's not > hardware-specific, I don't think it's there) Agreed, the config is already _very_ minimal for this machine. > Turning of the VIA sound driver just in case would be good too.

It definitely isn't heat related. This CPU puts out 7-10W, has a ridiculous 5000 RPM fan on it (that works) and the temp never exceeds 40C. If anything, the -O2, 3.4.6 kernel with CMOV ran the chip a little hotter. As far as I can see, all the other components are either cool to touch or have stupidly big heatsinks on them. (I realise with problems like these it's almost always some sort of obscure hardware problem, but I find that very difficult to believe when I can toggle from 3 years of stability to 6-18 hours crashing by switching compiler. I've also ran extensive stability test programs on the hardware with absolutely no negative results.) -- Cheers, Alistair.
