[uml-user] root_fs troubles.

[Thomas C. R. <th...@th...>]

Hey,

I managed to get UML working, but only with a very old 2.4.9 kernel.
The next step was to get the networking going, so i decided to upgrade
to 2.4.20 in order to do this. I followed the instructions on the
website to the letter, however, i now cannot start my UML, as i get the
following error:

VFS: Cannot open root device "ubd0" or 62:00
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 62:00

However, the root file systems are still there, and they check out OK
with e2fsck. The kernel has ext2 support built into it, so it should be
able to see it... I'm starting UML like this:

Kernel command line: ubd0=/extra/thomi/uml/umlroot
ubd1=/extra/thomi/uml/umlpart1 eth0=tuntap,tap1 root=/dev/ubd0

Is there something obvious I'm missing? AFAIK i haven't changed any
option with regards to file systems, so I'm completely stumped...
