booting 2.5.68 with root on software raid and devfs?

[Pierfrancesco Caci <ik5pvx@home.tippete.net>]

Hi,

anyone has an idea why 2.5.68 can't boot (it sends a panic, can't
mount root on md(9,0) message and dies) off a raid1+devfs setup that
works perfectly on 2.4.x ?

I have the suspect that something in the naming of devices has
changed, but I can't find any reference by googling around.

Here's my setup, as 2.4.21-pre7 sees it:

root@penny:~ # mount            
/dev/md/0 on / type ext3 (rw)
proc on /proc type proc (rw)
/dev/penny/niglia on /usr type ext3 (rw)
/dev/penny/viola on /var type ext3 (rw)
/dev/penny/tippete on /home type ext3 (rw)
/dev/kim/felix on /usr/src type ext3 (rw)
/dev/kim/isidoro on /home/ftp/pub type ext3 (rw,noatime)
/dev/gattaia/pink on /scratch type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)


root@penny:~ # cat /proc/mdstat 
Personalities : [raid0] [raid1] 
read_ahead 1024 sectors
md0 : active raid1 ide/host0/bus1/target1/lun0/part1[1] ide/host0/bus0/target0/lun0/part1[0]

      39896576 blocks [2/2] [UU]
      
unused devices: <none>

root@penny:~ # head /etc/lilo.conf
#disk=/dev/hda
# bios=0x80
#disk=/dev/hdd
# bios=0x81
boot=/dev/md0
root=/dev/md0
raid-extra-boot=/dev/hda,/dev/hdd
#compact
#linear
lba32


Any ideas where to start looking ?

Thanks

Pf
