Expected Results:  None of the above message!

Additional info:

I haven't checked with smaller swap space (could it help?).  Any ideas 
what's going on?

Comment 1 Arjan van de Ven 2001-06-25 17:50:44 UTC

Could you check kernel 2.4.3-12? This kernel has a lot of small bugfixes and
might fix this problem. (And yes, we REALLY REALLY load kernels before we even
consider shipping them)

Comment 2 Need Real Name 2001-06-25 18:04:17 UTC

I downloaded kernel 2.4.5, compiled it and installed.  It works fine, and, so 
far, none of the above problem.  I'm not too sure what fixed the problem, but 
it hasn't happen again!  (And yes, I have no doubt that you guys do extensive 
testing on the kernel before shipping them!)
