I have a quastion related to vanilla-sources kernel.

After upgrading vanilla-sources from 2.6.26 to 2.6.28_rc2 I am not
able to boot anymore. I tried playing with menuconfig couple of times,
but couldn't find what I have to change in order to make it work
again.

The error message while booting is like this:

Using IPI shortcut mode
BIOS EDD facility v 0.16 2004-Jul-25 1 devices found
VFS: Cannot open root device "307" on unknown-block(3,7)
Please append a correct "root=" boot option; here are the available
partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-
block(3,7)


Note that in my lilo.conf I have root=/dev/hda7 line for all kernels.

Thanks for any suggestion,
Marko

The 2 main things to look for are File System support & chipset. did you 
copy your
old .config and run a make oldconfig ? Shouldn't have been much to 
modify, if any.

My guess is that you would need to specify /dev/sda7 instead.

That filesystem support is not compiled in the kernel?

How do you know? The error is about block devices, not filesystems.

Are you sure that all drivers (chipset, disc) needed for booting are compiled 
into the kernel? Please post your .config + lspci output.

Have you tried root=/dev/sda7, i.e. "s" rather than "h", in lilo?  My
understanding is that disk driver changes in the kernel have resulted
in the replacement of IDE subsystem drivers with a "universal" (SCSI
based) subsystem.  A side effect of this is device name changes,
notably /dev/hdX to /dev/sdX.  I'm not sure that this is 100% accurate
because I don't track kernel changes as closely as some folks.

HTH,

David

Not replaced, the old one is still there and one has to select the new SCSI 
based drivers explicitely.

That's true, indeed.
