   It is 100% reproducible, and I cannot issue commands to kernel debugger, 
keyboard is dead.

   Enabling verbose boot helps, with verbose boot it boots to installer.

try to boot verbose

It is funny, but boot-verbose helps on battery and doesn't help with AC. I think, it is 
because with AC plugged in CPU is set to "performance" mode and delay from 
printing verbose information is not enough!

 Same panic with much more recent kernel, again, only if AC power is 
connected...
