mount: special device /dev/hda7 does not exist

I can no longer mount /dev/hda7. This problem surfaced when I switched from
gentoo-dev 2.6.7 to 2.6.8

This is the error message.

mount: special device /dev/hda7 does not exist

This is the output from fdisk /dev/hda.

Disk /dev/hda: 122.9 GB, 122942324736 bytes
255 heads, 63 sectors/track, 14946 cylinders Units = cylinders of 16065 *
512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 1037 8329671 c W95 FAT32 (LBA)
/dev/hda2 1038 1287 2008125 82 Linux swap
/dev/hda3 1288 14946 109715917+ f W95 Ext'd (LBA)

/dev/hda7 3380 14946 92911896 83 Linux

I can see that there is no hda7 in /dev, so I would guess it is something
simple having to do with devfs or udev. I don't understand either very well,
and I especially don't understand why switching to 2.6.8 would cause this.

I don't know if this would have anything to do with it or not, but I get
this error message on boot up.

rm: cannot remove '/dev/.devfsd': Read-only file system

Any help would be appreciated.

TIA.

Maybe you forgot to compile in you kernel the option to support your
filesystem...
Did you run a "make oldconfig" while switching kernel version?
What kind of FS is /dev/hda7 on? Are there other partitions with same
FS? Do you experiment the problem with this one only?
Please give some more details...

Cheers
Francesco
