Subject[PATCH] initrd fails again in 2.5.18
Date
From
The initial ramdisk fails to work with a slew of errors like:

generic_make_request: Trying to access nonexistent block-device 01:00 (2)

The problem was caused by change

kdev_t -> bdev cleanups [2/2]

which took out the ability of bdev_get_queue() to create a queue if one didn't
already exist for the device. The functionality was moved to
block_dev.c:do_open() where it exists within the if(!bdev->bd_openers) which
the ramdisk never gets to.

The (tested) fix, I think, is to set bd_queue as part of ramdisk
initialisation, which is what the attached patch does.
