can't reboot after running a 5.0 kernel

[Chuck Cranor <chuck%ece.cmu.edu@localhost>]

Hi-

    I've got a system that identifies itself as:

Digital AlphaStation 600 5/266, 266MHz, s/n 
cpu0 at mainbus0: ID 0 (primary), 21164-5


    It is currently running 4.0 fine (reboots cleanly, etc.).

    If I boot at 5.0 kernel on it and attempt a reboot, I get the 
following:

# halt
Jan 27 10:19:23 halt: halted by root
syncing disks... done
unmounting file systems... done
halted.


halted CPU 0

If I cycle the power, it boots fine once again.   My guess is that the 
5.0 kernel is leaving the pka0 device in a bad state.   I only get the 
"waiting for pka0.7.0.1001.0 to start..." errors after running the 5.0
kernel (4.0 kernel is fine).

Any ideas on what is causing this problem?
