Disassembly of the place that crashed (preferably with > -S if you have it) would be useful. It might have been some issue with just copying over modules. I installed a full kernel and the crash went away..at least for a bit. System crashed while I was driving home, but serial console is at work..so will check it later to see if it was the same issue. I'll build w/debug and dis-assemble it if the problem persists. Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
