Is there such an animal for Knoppix? Something like the one Windows XP has, at least.

(I'm having random lockups which may occur when the machine has been running for an hour or so idle, or when using it, occasionally.) I've been round the block for two years with this machine trying to find hardware errors. After an RMA on the motherboard, I thought I had it licked, but maybe not. Anyhow, it would be nice to have a log.

Thanks
