Decided to try out 2.6.31-rc4-rt1. Kernel Panic.
The panic is:
"Kernel panic - not syncing VFS: unable to mount root fs on unknown block (0,0)."
I checked the grub menu.lst and it has my root partition as hdb1, which is correct.
I've recompiled the kernel five times with various solutions from a google search, like disabling CONFIG_SYSFS_DEPRECIATED_V2, compiling reiserfs into the kernel, rather than a module and a host of other things.
I even tried using the .config file from the lenny 5.0.1 kernel.
It seems the problem is that an initrd file is never made.
I read this -rt kernel is a lot different from the former and I really want to give it a go. Any ideas are greatly appreciated.
