Please, build your kernel with debug symbols. > > 2. Show kgdb output I could not convince the kernel to dump (it was looping forever but not panicing), but I have managed to compiled a kernel with debugging symbols and DDB which immediately drops into the debugger when the problem occurs, see screenshot at: http://lukemarsden.net/kvm-panic.png Progress, I sense. I tried typing 'panic' on the understanding that this should force a panic and cause it would dump core to the configured swap device (I have set dump* in /etc/rc.conf) so that I could get you the kgdb output, but it just looped back into the debugger. This issue seems to occur very early in the boot process. I would like to invite anyone with the skills and the inclination to have a poke around with this directly over VNC to email me off-list and I will turn on the VM and send you the VNC credentials. My email address is: luke [at] hybrid-logic.co.uk Or you can catch me on Skype at luke.marsden. I'm in GMT+1. I look forward to hearing from you ;-) -- Best Regards, Luke Marsden Hybrid Logic Ltd.
