[syslinux] problem loading initrd

Hi,
I am trying to load kernel 2.6.6 on a Soekris net4521 from the network
using PXE. I built my initrd with mkinitrd. RedHat nash (while running
linuxrc) hangs after mounting /proc and says "Creating block devices". I
am using the pxelinux.0 from the syslinux-2.10 distribution and the kernel
and initrd were built on redhat 9.0. I built my kernel with BLK_DEV_RAM,
RAMFS, TMPFS, DEVFS_FS, BLK_DEV_INITRD, EXT3_FS and EXT3_FS support.
Attached below are:
- linuxrc
- contents of initrd
- pxelinux.cfg/<Soekris-IP> and
- kernel boot messages on minicom and tftp/pxe server.
Looks like the problem lies either with the kernel options passed to my
net4521 or with the initrd image itself. What should I do to make the
initrd load properly?
Please advise.
Thanks
Prabha
linuxrc:
