Hi!
We are building embedded devices based on Linux and we use a ramdisk as
our root device in order to avoid problems with people switching off the
unit without a proper shutdown and to save write-cycles on our flash disc.
Using a 2.6.12 kernel it was no problem to boot the system by using this
kernel parameters:
load_ramdisk=1 console=tty0 initrd=initrd.gz rw vga=769
ramdisk_size=32768 root=/dev/ram0
Today I tried to test run a 2.6.17.12 kernel using the same parameters
but I get this error message:
VFS: Cannot open root device "ram0" or unknown-block(1,0)
Please append a correct "root=" boot option
The RAMDISK driver seems to be initialized correctly and the initrd
image (gzipped ext2fs) contains a block device /dev/ram0 with major 1
and minor 0 ...
Any hints what has changed and how I can get this kernel to use a
ramdisk as its root device?
Thanks in advance,
best regards,
Heiko
