I am going to include this entire message because it is SO relevant.

me: 300 mhz eb164
128 MB RAM
2 MB cache
ncr 53c810 scsi
2 x quantum XP 34300 fast scsi 2 (non-wide)
trio s3 video

1. I wonder if we have too much (?) RAM
2. I wonder if our Atlas drives are incompatible with RedHat somehow
3. I need help! :)

Yep, everything except the part about having the CD on order, since I have
recieved NO REPLY at all to my continued requests for help, I plan to give
NOT A SINGLE PENNY to redhat ever again.

first, (this is during 3.0.3 and 4.0 installs) mkswap fails.
then, I test with a 40 MB file, you know, copy between partitions, drives,
whatever. unfortunately, the last time I did a test (which was a half hour ago)
it resulted in a (get this) 'bus error', and then (this is even better)
tcsh had a 'out of memory' error, and any virtual consoles sort of collapsed on
themselves... THEN, I got the old looping video bios to black repetition cycle
when I manually rebooted...(this is instead of the SRM... unplugging the
keyboard seems to clear this up.) THEN, when I booted milo, SRM explained that
it was 'jumping to bootstrap code' then hung. repeated attempts resulted in
same. this made me decide to reinstall. (why) with ARC+bootdisks, and it
totally flaked. I got a kernel panic, followed by a bogus address, then a total
hang (I'm quite used to the total hangs by now, thanks) Grr.

and I have looked for the 'latest and greatest' MILO, only found 2.0.12.

hmm, this confuses me, as redhat 3.0.3 was brain-dead, as well, with all kinds
of bogus addresses like the one above (f256539db2fa40d7a what the hell is this)
resulting in me 'upgrading' to another flaked out redhat....

I guess that would be me, but I have heard that 2.0.18 should be quite stable.
