Description Douglas Kilpatrick 2001-02-28 16:58:15 EST
I've seen three different people mentioning the problem, but could not find
a bug report, so I thought I'd make one...

My problem:

Did a "fisher" install.  / is a RAID1 partition (lots of RAID partitions
actually... )  With the fisher kernel, boots fine.

Updated kernel to wolverine kernel.  Boot fails, "isofs_read_super: bread
failed" and "Kernel panic: VFS: Unable to mount root fs on 06:01".  I'm not
at the computer right now, so I'm not sure of the numbers in the unable to
mount message.

The old kernel spews out lots and lots of debugging messages when the raid
modules load and autodetect the raid arrays.  The new kernel spits out
nothing and does not appear to find my raid arrays.

Bug 29731 references this problem, as do a couple of posts in the wolverine
mailing list.

System is a KT133A-based AMD T-Bird.  (Asus KT133K7V or somesuch).  3 hard
drives, two on the promise controller, one of the via controller.  / is
split over the via (hda) and the promise (hde).
