Does this happen after suspend/resume by any chance? I ask because it looks vagely similar to http://groups.google.com/group/linux.kernel/browse_thread/thread/7aa897981d7d440f . The first error is interesting, the other ones look like slab lists have been hosed. Just to rule it out, have you run memtest+ on your machine to make sure you RAM is healthy? > Sep 19 17:05:33 tweety kernel: BUG: unable to handle kernel paging request at virtual address 07e07fbc >
