Hi, I've got a serious problem with my ibook/G4. Since yesterday there are frequent kernel crashes. No chance to get the system up without a kernel crash. Booting in single user mode usually works, probably because of much less disk io. As soon as larger processes like postgresql or X11 are started the system ends up in xmon, which in some cases be left with 'x'. This happens for linux 2.6.8 (stock debian kernel), 2.6.9 and 2.6.11-rc4. They all had been working till yesterday. I initially suspected my daily apt-get upgrade, but that is very unlike to be the case, because starting the ubuntu live cd has identical problems. I never get into X but usually have a console to log in. If I execute 'dd if=/dev/hdax of=/dev/null' it almost freezes imediately. Running a fsck is impossible. It freezes before reaching 10%. MacOSX is working as usually and even reading one of the linux partitions with dd or mounting them from MacOSX with ext2fsx didn't cause any problems. I'm not sure what is going on, but I'm under the impression that this is hardware related. The last time it run reliable (yesterday) it has been under heavy load for at least 4 hours with the fan on almost all the time. I can't believe this has overheaded it, but how knows. I added some syslog messages at the end of the mail, just in case it helps. I'm completely clueless and I don't think apple will care about it as long as it runs under MacOSX. Any help welcome.
