Subject: (Sparc64) 2.6.20 seems to ignore initramfs
Date: Fri, 23 Feb 2007 11:08:10 +0000 [thread overview]
Message-ID: <200702231108.10185.andrew@walrond.org> (raw)
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...
PROMLIB: Sun IEEE Boot Prom 'OBP 4.23.0 2006/06/02 16:14'
PROMLIB: Root node compatible: sun4v
Linux version 2.6.20 (nobody@spawn1.secure) (gcc version 4.1.1) #1 SMP Thu Feb
22 16:25:18 GMT 2007
ARCH: SUN4V
Ethernet address: 00:14:4f:2a:90:92
PROM: Built device tree with 65903 bytes of memory.
Built 1 zonelists. Total pages: 242541
Kernel command line: ro
[snip]
checking if image is initramfs... it is
Freeing initrd memory: 124934k freed
[snip]
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.
