pcspkr beep causes machine check on g5
Last modified: 2007-11-30 17:11:16 EST
Loading the pcspkr module and doing something which causes a beep (ctrl-g on the
console, anaconda beeping to say the install is done... ;) leads to a machine
check on my G5 with 2.6.14-1.1632_FC5
You mean like a "Machine Check Exception?"
Is there anyway you could run mcelog and paste the output?
ppc64 mce's aren't parsed by mcelog.
at a guess pcspkr is poking some port that doesnt exist on ppc
pcspkr got disabled in current ppc kernels.
