When I tryed to boot with qemu a 2.6.24-rc2-git5 with sysfs disabled,

Kernel panic - not syncing: VFS: Unable to mount root fs on

From CONFIG_SYSFS help text:

sysfs is currently used by the block subsystem to mount the root
partition.  If sysfs is disabled you must specify the boot device on
the kernel boot command line via its major and minor numbers.  For
example, "root=03:01" for /dev/hda1.


Shame on me :)
Thanks a lot.
