Hi to the list, I'm running the 2.6.14-rc4 kernel with realtime-preemption (rt1) patch on a debian testing/unstable. I was trying to create a simple sessione with lash, lash_synth and patchage but qjackctl died suddenly. In syslog I've found the "stack trace" of the kernel due to a bug, something that begins with: localhost kernel: BUG: Unable to handle kernel paging request at virtual address 00100100 and then continues for more or less 100 lines of additional informations. Looking in syslog I've found also another 2 o 3 _different_ bugs: they are all audio related. Are those syslog information useful for debugging? How and where should I report them? Now I will try If I can reproduce the bug with the vanilla 2.6.13 kernel and/or with the 2.6.14-rc3-rt2 that I've previously compiled. Best Regards, ~ Antonio
