But the raid-0 array didn't work. The boot scripts tried to fsck it, but couldn't get a valid ext2 superblock. (fsck -f under 2.5.69-mm8 showed no problems, the fs was clean.) Then it was mount time. Various partition and raid-1 based fses mounted fine, but mounting the raid-0 on /usr/src killed the kernel: unable to handle kernel NULL pointer deref at virtual address 00000014 PREEMPTSMP EIP at raid0_make_request process mount bh_lru_install generic_make_request autoremove_wake_function bio_alloc submit_bio __bread_slow_wq __bread ext2_fill_super sb_set_blocksize get_sb_bdev alloc_vfsmnt ext2_get_sb ext2_fill_super do_kern_mount do_add_mount do_mount copy_mount_options sys_mount syscall_call Looks like something else is wrong with raid-0. > I have jsut sent some patches to Linus (and linux-raid@vger) which > will update his tree to include this fix. > Were there anything more than removal of the two kfrees?
