Well - interesting.
Thanks to these replies, I learned to use "linux single" at that boot:
prompt
That got me in a shell, along with this error:
The superblock could not be read or does not describe a correct ext2
filesytem. If the device is valid and it really contains an ext2 filesystem
(and not swap or ufs or something else), then the superblock is corrupt, and
you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
fsck.ext3: Filesystem revision too high while trying to open /dev/hda2
eek, I say. so I said oh alright and entered:
e2fsck -b 8193 /dev/hda2
and got the same superblock error
so I referred to Jan's email and typed:
fsck /dev/hda2
and got the same superblock error
so I said hmm and tried:
fsck /dev/hda
and got a similar superblock error only it mentioned ext2 - odd?
and that's where I'm stuck currently - worried that I've got a hardware
malfunction :)
here's the caveat: last night before hearing back from anyone, I, in my
grand wise impatience, booted with the red hat cd and entered the rescue
mode. there, per instructions I found in an archived email, I attempted to
mount hda2 and it said the device doesn't exist. eek. so then, in my GRAND
GRAND wise impatience, I decided to let Red Hat CD install a new OS, while
keeping all partitions and just using free space. during this install
process, I got error messages while reading hda - i hobbled through the
process, let it reboot, and came out with the same kernel panic, which led
me to believe I was having a harddisk screw up. then I went to bed and got
up and tried the above.
Aaron will be backing up more often from this day forward. :)
ideas?
