Hi,

the attached patch (created against 2.6.30) makes the kernel harder
finding a valid root device.
Changes are:
- New kernel option alt_root=<alternative root device>
- If an alternative root device is defined with alt_root, e.g.
alt_root=/dev/sda1, and the primary root device could not be found
because a) root device is defined by it's UUID and b) initrd is missing
or damaged, then the kernel will try to use /dev/sda1 as it's root
device.
- If an alternative root device is defined with alt_root and initrd is
damaged then the kernel will try to use /dev/sda1 as it's root device.
