Description Jeremy Katz 2005-10-28 15:26:59 UTC

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

Comment 1 Dan Carpenter 2005-10-29 06:21:45 UTC

You mean like a "Machine Check Exception?"

Is there anyway you could run mcelog and paste the output?

Comment 2 Dave Jones 2005-11-04 21:22:33 UTC

ppc64 mce's aren't parsed by mcelog.

at a guess pcspkr is poking some port that doesnt exist on ppc

Comment 3 Dave Jones 2005-12-01 07:14:51 UTC

pcspkr got disabled in current ppc kernels.
