[ILUG] Problem booting 2.6 kernel

[Kevin Houlihan]

Hi all

I've been trying to upgrade to a 2.6 kernel, but no matter how 
I set up the config, I get this error when I reboot:

VFS: Cannot open root device "306" or unknown-block(3,6)
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on unknown-block(3,6)

I never had this problem with my previous kernel (2.4.26), and the 
precompiled 2.6 kernels from Debian seem to work ok. Any ideas 
what this relates to?
