On a Sun T1000 I am trying to boot 2.6.20 using initramfs. (I use the same
procedure successfully on x86_64 and itanium2 servers).
The relevent silo section looks like this:
image=/boot/2.6.20.image
label=2.6.20
initrd=/boot/2.6.20.initramfs
partition=2
read-only
The kernel loads and boots and I see
Allocated 8 Megs of memory at 0x40000000 for kernel
Loaded kernel version 2.6.20
Loading initial ramdisk (127932430 bytes at 0x1000000 phys, 0x40C00000
virt)...

Remapping the kernel... done.
Booting Linux...

checking if image is initramfs... it is
Freeing initrd memory: 124934k freed

VFS: Cannot open root device "<NULL>" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
<0>Press Stop-A (L1-A) to return to the boot prom
So it knows about the initramfs, but then tries to mount a root filesystem
instead...
I haven't tried this (initramfs) with earlier kernels, so I don't know
whether this is a regression. Any clues about how to solve this would be
greatly appreciated.
