mount: unknown filesystem type 'devfs'

kfir_w · 06-15-2007, 05:13 AM

Hi,
I am a NEWB, using Ubuntu 7.04 and have recently compiled the new 2.6.21.5 kernel.
When trying to boot the new kernel I get the above message followed
by "kernel panic: not syncing..."
I read some threads about udev that is supposed to replace devfs
but have no idea what any of them mean and how to actually do it.
I find nothing about devfs in the kernel .config options.

Please help!

Thanks,
Kfir

If kernel can't mount a filesystem on boot it means you should recompile it and compile a driver for this filesystem IN kernel (I mean no modules).

Thanks for the reply,
I believe the problem is indeed in the kernel itself, since my old kernel works without this error.
BUT (there is always a but)... I don't know which driver to compile in the kernel. Can you tell me what is the driver for devfs?
I configure the .config file using 'make xconfig'.
