Hi,

   So far I have got this additional info from the console when the  
server panics:

cpuid = 0
Uptime: 19m57s
Sleeping thread (tid 100024, pid12) owns a non-sleepable lock
panic: sleeping thread
cpuid = 0
Uptime: 19m57s
kernel trap 12 with interrupts disabled

then follows the same text I originally posted...
Im going to run this again and try check if any other info is printed  
but scrolled off the top of the screen...

thanks Andy.
