Hello.

Since yesterdey, every time I run a 2.4.9 or 2.4.10pre-4 without the 
"devfs=nomount" I
have two oops + /usr, /home /boot not mounted (all (also /): ext2).

2.4.9 worked fine before, thus maybe the cause is one of the new userspace
packages I updated. But anyway OOPS are kernel problems.

 Attached: the two oops and the output of dmesg and of lspci -vvv.

The system is pure (I've removed the nvidia module, but it change nothing)
(I need nvidia driver until xfree will support geoforce2, hoping that
nvidia will release all info about my card)

If you need other infos, ask!

    giacomo
