We have an application under development at Yahoo! which can provoke a
similar crash on an N440BX-based system running 3.3-RELEASE in about half
an hour. The application is both disk and network intensive--under test
both are pretty close to being maxed out. Although crashes most frequently
occur during fxp interrupts, this is not always the case; what IS always
the case is that stack variables are getting clobbered.
We've been able to compare identical configurations except for SCSI
vs. IDE. Only the SCSI (using the on-board Symbios controller) system
has failed so far. This failure has been replicated on several boxes
(it's not just a single bad board). A 2.2.8 system with identical
hardware (including SCSI) running the same application doesn't seem to
be failing. More testing is required to establish this pattern with
certainty, however.
Peter Wemm is up here in Santa Clara and is studying the problem as I
write. More information will be upcoming...
