The in-memory core dump facility, Kernel Core Dump v2.0, is available
for
kernel version 2.3.41 for Alpha. An updated Core Analysis Suite is also
available.
Attached is a sample stack trace for a (forced) memory fault in the
tulip interrupt
handler on processor 0, and an idle processor 1. These tools may be
found at
