Hi all,

Can anyone take a look on PR kern/104406 ? I got repeatable hang situation, but I can't obtain a kernel dump to get result of all 
show commands from here:

After my break to debugger using Ctrl+Alt+Esc sequence and entering a "panic" command kernel does not wrote a kernel dump but seems 
to hang. Can anyone describe how to obtain a kernel dump in this situation, or at least say - which output of show commands need in 
first place to debug this ? Output of all suggested commands is huge and I afraid of making mistake when carrying this output from 
screen to list of paper and back :-)
