[CentOS] How do we handle panics? Bug it here or RH or ignore
it (been around *long* time apparently)?

Haven't stayed running long enough to pursue this (did take time for
real life stuff, seems more manageable)

Have tried several combinations without success. Swapoff, 0

Am currently running with swappiness at 10, swap enabled both readaheads
disabled. This is all the stuff that was gleaned from the prior CentOS
Anyone got any other things I might try? I know a fix is not yet
available (if my googling was extensive enough and I missed nothing) but
I would like a work-around that might keep it up more than 24 hours
about 90% of the time.
One new piece of info: a lot of the OOPS, but not all, have started
after the machine was idle and I touch the keyboard to bring the things
back to life (AFAIK, just a screen-saver, blanked, going). So I turned
off the BIOS ACPI stuff. Since I know zilch about the ACPI stuff, I've
begun reading /usr/share/doc stuff (kernel params and pm) to see what I
might disable in there. Maybe that will help some.
But if anyone has a couple suggestions regarding that, I might get the
docs read faster (fewer boots). I would appreciate it.

Since I'm somewhat new here, and this is a recognized problem in the
community (if my googling is correct), I am still uncertain how I should
deal with this, other than the workaround. Can someone please respond to
my simple question: "Do I bugzilla CentOS, RH or ignore it?"
