Hi, I am trying to mount /dev/hda0 (the first partition on /dev/hda) as my ext3 root filesystem during boot. Even though I can mount this partition after boot and successfully see the files on it, (using "mount -text3 /dev/hda1 /mnt/disk1" and hda1 with major 3, minor 1) the same partition cannot be mounted as the root filesystem during boot. I get the error: VFS: Cannot open root device "0x301" or unknown-block(3,1) VFS: Cannot open root device "0x301" or unknown-block(3,1) Please append a correct "root=" boot option Please append a correct "root=" boot option <0>Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1) Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1) In kernel bootargs, I tried root=/dev/hda0, /dev/hda1 and also root=0x301 (major 3, minor 1) to mount it. It should have just worked. Any idea why it doesn't?
