Hi,
I have been trying to get IXP425 based coyote board to boot with 2.6.8.1 /
2.6.9-rc3-ds1 with mtd-snapshot-20041005. I have selected jffs2 to also be
updated from the snapshot.
However at bootup I get:
Kernel panic - not syncing:VFS: Unable to mount root fs on
unknown-block(31,2)
The root on flash is a jffs2 filesystem and I pass root=/dev/mtdblock2 as
my kernel parameters.
The partition mounts fine when I boot using NFS and do a manual mount. It
also works fine as root on a 2.4.19-ds3 kernel that I have.
Tracing through it seems get_fs_names() in mount_block_root() in
init/do_mounts.c fails.
Any idea what is causing this ? Any suggestions where I should be looking
for the cause of the problem.
Thanks,
Prashant Alves

pass rootfstype=jffs2 in the commandline
