Hello,
I encountered an oops on a disk with bad blocks while making
a backup from another machine via nfs to that machine (the
oops machine "atlanta" is nfs server).
The oops is:
Nov 13 03:48:37 atlanta kernel: hda: dma_intr: status=0x51 {

The kernel is
Linux atlanta 2.4.15-pre1 #2 SMP Fri Nov 16 23:08:06 CET
2001 i686 unknown
and the disk is "IBM-DTLA-307075" (is that drive known for
failures?)
Is that bug known?
Is the filesystem in a state so that it needs a reiserfsck,
or is it sufficient to delete the data whose data or
metadata touches the bad blocks?
If a reiserfsck is needed, is there a ramdisk distribution
(kit) which allows you to do the work completely from the
network?
