PK6 Causes Panic

OSF1 mcgcrc1 V5.1 1885 alpha on DS20

Hello,

On Tuesday I installed PK6 on my Alpha running 5.1A. The entire patching
process seemed to run okay, and it ended with a rebuilding of the kernel.
On reboot, the system panicked and restarted itself. I managed to boot using
the old kernel, and everything is okay now. 

Here is the error log of the panic.  Anyone know what to make of this? There
were other EVM alerts similar to this one, at least one per boot attempt. 

Thanks,
