CRASH! #17

Open monkeypants opened 9 years ago

monkeypants commented 9 years ago

Twice, I crashed the kernel tonight. Failed to photograph the screen (my bad). One had SMP kernel errors (I don't need SMP!) and the other time there were nvidia driver errors (not using the proprietary drivers, the nv one).

Can I compile a kernel without SMP? I don't know how to compile a realtime kernel. This might improve jitter if I built a monolithic kernel with everything I truely need and nothing I don't.

Can I just get a better video card (non-nvideia)?

Both crashes came soon after "linuxcnc is already running; do you want to restart it" - "Yes". Maybe that's a coincidence. Or maybe it's caused by trying to start two RT threads, or loading the RT module twice, or something like that (if so, don't do that then).

have reproduced this again, always after trying to start LinuxCNC after not shutting it down cleanly - so don't do that then, Have not tried to reproduced it with new-build from source. Never seen it after starting the first time after a boot. Suspect issue with RT Kernel (e.g. loading part of it twice)
