Before doing this, I ran the dellmgr program to reconfigure the raid. Before the "oops" text, I saw: Badness in remove_proc_entry at fs/proc/generic.c:688 [] remove_proc_entry+0x10a/0x150 [] megaraid_exit+0x2e/0x3e [megaraid] [] sys_delete_module+0x150/0x1a0 [] do_munmap+0x140/0x190 [] syscall_call+0x7/0xb That above explains the few lines above "Unable to handle kernel paging..." This system boots via NFS and / is nfsroot. There is no swap setup on the machine since there are no local disks. The raid there for testing before moving it to another machine. The system has 384mb of physical ram. Oops follows: ksymoops 2.4.9 on i686 2.6.8.1.
