From: Fernando Pablo Lopez-Lezcano <nando(a)ccrma.Stanford.EDU> Is anyone out there trying out this combination?: kernel 2.4.20-rc1 capabilities patch low latency patch preemptible kernel patch almost current alsa cvs [20021028.170432 usa pacific time] If I start jackd and then use the freqtweak jack client I get a completely dead machine in a very short time (from a few seconds to 10 or 20 seconds). ... Interestingly enough just the jack server running is not enough to kill the machine. Adding a jack client (just tried alsaplayer, same problem as freqtweak) kills the machine really fast.
