unable to boot from srm

hi

i just installed suse 8.1 on a as4100 and trying to
boot from srm console, with no luck.

my setup looks like:

fdisk /dev/sda
3 partitions:
#       start       end      size     fstype   [fsize bsize   cpg]
  a:        6        21        16       ext2
  b:       22        86        65       swap
  c:       87       521       435       ext2

/dev/sda3   /      ext2
/dev/sda2   swap   swap

at the srm-prompt i do: boot dkb0 "root=/dev/sda3"

then the machine is boot until it stop with a kernel panic, an says
i have to specify "root=". but that's what i did as you can see.

whith the rescue system i'm able to boot with sda3 specified as root.

what i'm doing wrong here ?

thanks, markus
