VFS: Cannot open root device "cobd4" or unknown-block(117,4)
Please append a correct "root=" boot options; here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(117,4)
I try to use my dual boot WinXP-Linux. WinXP SP3, SUSE 10.3, Colinux 0.7.3.
This is a new installation after HD fail for SUSE, but WinXP was cloned. I used same config in fail HD (SP3-10.3-0.7.3). When I stop SUSE, or when I start Colinux-Monitor, all device cobdx was deleted. I don't understand why, and I don't remember any problem like this 1 year ago.
Do you use partitions? Then, it can be, that your partitions are in other order.
Check it with the "dd.exe --list" from Cygwin tool on your Windwos prompt.

I have trouble with step B. Create /dev/cobdN devices in the linux partition
I created device. And when I reboot SUSE, device disappear. I think, it's a new feature in device management in SUSE.
I solved my problem. I think udev removed my devices, because this is not real device (no hardware). I created same devices in /lib/udev/devices, and after a reboot, devices appear in /dev.
