Re: Will setting LD_ASSUME_KERNEL=2.2.5 fix constant RH9 crashes?

Unfortunately the answer is "all of the above". :)  I do not think I
have experience a kernel panic yet, as in all cases I have still been
able to ping the machine.  So far I've experienced the following:

- Kernel drops all support for USB.  This is bad when you have a USB
keyboard and mouse.  This has happened several times on different
machines.  Plugging in a PS/2 kybd lets me reboot.
- Complete freeze.  X stops working, cannot switch to console.  Cannot
SSH into machine.  Machine still responds to ping.  This has happened
twice, but only on one machine so far.  (The other machine is at home,
and has thus far been rarely used).
- X crash.  Running Matrox Millennium 2.  Haven't seen one of these in a
while (never w/8)
- Java does crazy things.  Sometimes it crashes, sometimes my servlet
container can't extract JAR archvives.  Other weirdness.  Never saw this
w/8, and I'm running the supposedly approved Sun 1.4.1_02 VM.

I haven't seen a greater-than-average amount of trouble from staticly
linked apps, to the best of my knowledge.

Both my 9 machines are Athlons and are completely or almost completely
SCSI.  The hardware is all higher-end, well-supported stuff.  Neither
box had issues w/8, one of them had an uptime that is roughly equal to
the number of days between the RH8 release and the RH9 release.

Thanks for any help
