Unfortunately, I wasn't very scientific about it, so it could be one of two
things...
As it turns out, I had made a GRUB boot disk during my bout with the
Uncompressing Linux...Ran out of data...System Halted issue. And that disk
was still in my drive while I tried some things today:
-compiled the 2.4.13 kernel <-- I saw something in the changelog about SMP
which I did not understand; since I am using a dual-processor system, maybe
that fix had something to do with it?
-updated my 0th GRUB menu.lst entry to point to the 2.4.13 kernel
-added a "fallback 1" line to GRUB menu.lst to cause it to (hopefully?) fall
back to 2.4.3 if things didn't work out, again
The thing kept booting into 2.2.17mdk-smp ("wonder why!? maybe my GRUB's
been the problem all along!" <-- no, stupid, you have a floppy in the drive
from which the system is booting). So I got a new version of GRUB sources,
and installed. Rebooted, saw 2.2.17mdk-smp, and realized what was going on.
Took out the disk, rebooted, now I'm in 2.4.13.
I do know that kernels between 2.4.9 and 2.4.12 did not work for me. OR my
old GRUB (.5.95) was really at fault and .90 fixed it.
