oops on boot w/ lvm root & xfs

oops on boot w/ lvm root & xfs

[steve j. kondik]

i'm not sure if this is a devfs problem of an xfs problem.
i'm using an initrd to set up my lvmroot.  devfs complains then
panics.  all versions of 2.4.17 that i've tried (rc1, rc2, final)
will not boot.  2.4.16 runs fine.  help :>

devfs: devfs_do_symlink(root): could not append to parent, err: -17
change_root: old root has d_count=2

here's the ksymoops (i copied this by hand- i hope its right)

Hi,

it looks  like the same problem that i had, maybe take a look at the 
"OOPS  at boot in 2.4.17-rc[12]  (kernel BUG at slab.c:815) maybe devfs" 
thread.

Best regards,

Gregor Suhr
