'panic: RAM parity error, likely hardware failure.'
This one had me confused at first, because it blamed a RAM parity
error. As this is a brand new machine (Gateway GP-800), so I first thought
I got a bad batch. Then I realized this only happens with apps that try to
do sound stuff. It's also doubtful that it's a RAM parity error due to the
severe compiling workout I've given it in the last 24 hours (134 ports, a
few kernels and several attempts make world).
Unfortunatly, since this machine was installed with
yesterdays build to begin with, I cannot confirm whether or sound works on
older builds (if needed for testing, I can rollback to an earlier kern
revision..). I can get it to crash just by playing mpg123 or restarting
esd.
