Kernel bug?




I have one machine that's consistently crashing with what appears to be a kernel bug. At the moment it's running kernel-2.6.16-1.2111_FC4 . Before that it was running 2107_FC4 (I skipped 2108_FC4). Both kernels produced the same type of kernel message. The weird thing is that sometimes it will lock up the machine and other times it will continue to work just fine. I've attached a txt file with the latest one (and I realize that because of it being text, it will probably just get attached inline into this message.)

Anyway, if someone can shed some light on this, I would very much appreciate it. Thanks.
