I opened up jack-rack to see which plugins I was using, and try as I might, I wasn't able to duplicate either the high CPU utilisation, or the XRuns. A bit later on, the problem came back. I've also discovered that some of the plugins I've been using don't appear to work for me today. I think I might have broken something, but don't have time to dig deeper at the moment. I'll look again when I get back off vacation. For the record, I'm using 2.6.11.4-21.10 from SUSE 9.3 (which has the desktop and bootsplash patches among others) patched and recompiled with realtime-lsm using: http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12-rc4/2.6.12-rc4-mm2/broken-out/rt-lsm.patch Thanks for your interest. -- David Haggett
