Hi Thomas!
Well, I thought it was a good idea to test the rt patch.
Never did that before. Cyclictest output looked great, but then
i tried to do some audio recording. I used "chrt 80 arecord ..."
to record at 96kHz/16bit stereo from an RME Digi96/PAD.
That seemed to work fine on an idle machine. So I put
some extra load on the machine. A "make -j 16" kernel
compilation locks keyboard and screen within minutes,
no matter if X is running or not. The attached part of
/var/log/messages shows two of those events - I deleted all
but the very first log entries.
Hardware:
Aopen i915GMm-hfs, RME Digi96/PAD
Meinberg PCI32 DCF radio clock,
2GB RAM, Pentium M 1.86 MHz.
Software:
opensues 11.2 MS 7, kernel 2.6.31-rt10,
reiserfs partitions.
cu,
Knut
