Hi, I'm currently in big trouble because my iBook/G4 (bought a couple of weeks ago) is crashing all the time. There has been occasional crashes in the past which I thought were related to the sleep support and linux-wlan-ng. Since yesterday it crashes during file system check of any partition. I managed to disable the file system check after booting the ubuntu live cd. That has been a hassle as well, because of various kernel crashes. Currently I don't get the system up, unless in single user mode or with disabling many daemons. Whenever a larger process starts like postgresql or X11 it goes into xmon. Sometimes I get out with 'x'. I tried various kernels 2.6.8, 2.6.9, 2.6.11-rc4 and the symptoms are always identical. MacOSX boots just fine. Anyway, this somehow looks like a hardware damage, because the system has been fairly stable for some weeks running 2.6.11-rc4. Would be great if somebody had an idea what is going wrong.
