I'm having a terrible time recovering from this.   I tried fsck -f
repeatedly, even when it reports filesystem clean, it won't let me remount
rw.  Went thru 4 cycles of fsck and reboot to single user mode, with no
difference.  Only when I run dmesg can I see it still has XT_GETPAGE errors
(because it can't write to log files).  It finally occurred to me that
jfs_fsck might be different than fsck (silly me - I thought fsck would call
jfs_fsck).  I had to run jfs_fsck -f 3 times to fix it, and reboot before I
had a writeable root.    I had compiled 2.6.13.4 on another writeable
filesystem.   When I could write the new kernel to root, it rebooted with
"root not found", even tho the address md(9,0) was correct.  Fortunately, I
could still reboot on 2.6.12.3 and I will try again tonight.

Is the file system on an lvm or other device-mapper volume?  If so,
there was a data corruption bug that was fixed in 2.6.12.4 that you
might be hitting.

Please upgrade to 2.6.12.4 as well, and see if the problem persists.
