After the upgrade from RH8 to SL304, most
of our few stability problems seem to have
gone away.  However, we gained some new
stability problems.

We have 10 systems that ar eover two years
old that have never given us a single
problem, no matter how hard we flogged
them.  These are 2.4GHz P4 systems using
the Intel D845PE boards (no onboard LAN,
audio or video).  They all have some form
of 3Com 509 and a variety of video cards,
including S3 Virge, ATI and Matrox.

Since the SL304 upgrade a couple of months
ago, 7 of these boxes have locked up or
shown a kernel panic, most of them more
than once, two on an almost daily basis.
The shop who builds our systems can't
find anyhting wrong with them, and ran
the two that die daily here for two weeks
at their shop with no glitches.  All their
diag tools run under Windows or DOS) so
this appears to be OS-related.  (Other
systems on the same UPSes show no problems,
so it's not a power issue).

It can happen when they're really busy
or (it seems) even when they're idle.

I wondered about microcode issues; the
microcode_ctl startup task is on and the
logs show it ran:

   Oct 25 10:24:48 sim026 kernel: microcode: No suitable data for cpu 0

There's nothing suspicious in the logs;
they just lock up.  Both systems that
locked up today had the CAPS LOCK and
SCROLL LOCK keyboard LEDs flashing.

Has anyone else seen anything like this?

Our AMD systems are all fine, and the
other Intel boxes (faster SuperMicros
using I forget what board) are fine...

Thanks,
Miles
