2.5.19 - 2.5.21 don't boot with devfs

[Duncan Sands <duncan.sands@wanadoo.fr>]

Starting from 2.5.19 (x86), booting fails at "Checking root file system..."
if devfs is mounted; there is no problem if devfs is not mounted.  With
devfs mounted I get:

...
Checking root file system...
fsck 1.27 (8-Mar-2002)
...
fsck.ext3: No such file or directory while trying to open /dev/hda2

Here is my fstab:

# /etc/fstab: static file system information.
#
# <file system>	<mount point>	<type>	<options>			<dump>	<pass>
/dev/hda2	/		ext3	defaults,errors=remount-ro	0 1
/dev/hda3	none		swap	sw		        	0 0
/dev/hda1	/windows	vfat	defaults,user,exec		0 2
proc		/proc		proc	defaults			0 0
none    	/proc/bus/usb	usbdevfs	defaults		0 0
none		/devices	driverfs	defaults		0 0

Any ideas?

Duncan.
