>Description:
Installed 5.0_STABLE on an API CS20 / HP DS20L & then booted a GENERIC.MP 
kernel.  SSHd into the machine, downloaded the latest pkgsrc.tar.bz2, and 
proceeded to uncompress it.  About 70% of the way into it, the machine promptly 
hard locked.  No response is given on the network, or the serial console.  Not 
sure how to debug w/o serial console.

Michael L. Hitch documented this issue when fixing PR #41106, however no PR 
seems to have been created for this problem.

On a side note, the machine was setup using FFSv1 + WAPBL.  When rebooting, it 
appears that the filesystem was hosed.  Not sure if this is related or not.
>How-To-Repeat:
Use a MP kernel on an Alpha.
>Fix:
Unknown.  Not sure how to debug w/o serial console.
