All, I have isolated the crash to the following dd command: dd if=/dev/mem of=/dev/null bs=1024k skip=4040 count=1 I'm trying to think of a way to obtain more diagnostics. It looks like truss is broken due to the the lack of /proc in 5.3. I'll compile a kernel with procfs and see if I can obtain more detail trussing the dd. I really need guidance from the list on how to proceed and obtain more debugging info. Thanks, Gary
