Repeated crashes in 2.0.27/8 lately (incl. trace output).

Been getting two or three hard lockups per week lately in 2.0.27 and
.28, usually with little or no warning (nor any log messages). All seem
to occur during heavy access to an external 4GB SCSI disk that I have
hanging off of an Adaptec 2940 controller.

Last night's lockup was nice in that I got lots of advance warning and
logging information from it. (I'm working on development of an
astronomical software package here [AIPS++] that takes 24-30 hours to
compile; I started the compile around noon on the 26th, and the kernel
stack corruptions started almost immediately. The lockup was ~24 hours
later.) System is Red Hat 4.0 (with appropriate update patches), kernel
2.0.28 in this latest case. Any other info. anyone might want/need can
of course be provided....
