patch-2.6.15-rc7-rt2 (realtime-preempt) report

[Nedko Arnaudov]

Hi, just got rc7-rt2 tested. cdrecord test still freezes my machine but
this time I got screenshot(attached). Again I'm hiting this BUG only
when doing actual burn, not when I erase.

With rt2 my machine does not freeze with pmidi 1.6 anymore. But I get
this, when running pmidi 1.6 or tse3play (both using rtc I think):

I've not observed nothing bad except that dump however.
