This driver transition causes the device names to change from /dev/cciss/c0d0p1 to /dev/sda1. Thus, it would be really nice if UUID / LABEL / udev worked, as it would make it possible to boot kernels above and below 2.6.37. == Here comes the BUG and work-around == The BUG is that, if I compile the kernel and include the CCISS driver (even-though it will not be used), then initramfs will drop me into a shell, complaining that it cannot find /dev/disk/by-uuid/... The work-around is, either 1) to avoid using initrd images, or 2) don't compile the kernel with the CCISS driver. == Maintainers tasks == I suspect the bug lies in initramfs-tools, or the udev version used by initramfs-tools. Could the maintainers of initramfs-tools and udev, please tell me something like its fixed in version XXX, and the Debian maintainers just need to compile initramfs-tools with this version to fix the issue? ;-) initramfs-tools Version: 0.98.8 udev Version: 164-3 ps. I'm testing with net-next 2.6.38-rc5-02558-g07df529 -- Med venlig hilsen / Best regards Jesper Brouer ComX Networks A/S Linux Network Kernel Developer Cand.

It was decided that no overlap should exist. All new controllers will use the hpsa SCSI based driver.
