Subject[BUG] kernel 2.6.15.4: soft lockup detected on CPU#0!
Hi All,
i was trying to rip a CD when the whole machine started to freeze
periodicaly, i then looked at the logs and found the following :

After a few seconds, the whole machine was totally locked up and the
only option i had was a hard reset.
I was able to reproduce it once more.

I'm running vanilla kernel 2.6.15.4 on an athlon 32 bits. here's generic
