User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050909 Fedora/1.0.6-1.2.fc4 Firefox/1.0.6
Description of problem:
The kernel panics as soon as I press enter to boot at the installer's prompt.
First time it complained of a bad /dev/hda2 partition (can't recall the exact message). Since that drive had been used for debian before, I wiped the whole drive, restarted (rebooted w/ the FC4-x86_64 dvd) with a blank /dev/hda and then it panicked with this message:
VFS: Cannot open rrot device "<NULL>" or unknown-block (3,2)
Kernel panic: not syncing VFS Unable to mount root fs on unknown fs on unknown-block (3,2)
