I set the the dumpdev in /etc/sysconfig to /dev/sd0s1b. On panic, it enters DDB. When I press c, is says dumping to dev 20401 offset 104576 dump 40 ahc0: board not responding and the goes on with sync,shutdown. Any help appreciated. Thanks, Martin P.S. The causes of the panic where 'unmount: dangling vnode' and 'FPU device not available in kernel mode', respectively. I don't know whether dumping is possible in all cases.
