Over the past few weeks I've had continuous problems booting
my 5-current system with an SMP kernel.  Immediately after
the system has booted and the login screen displays the machine
panics.  The motherboard is an Abit BP6.  Below is the information
provided when it locks up.  Based on the kernel panic FAQ I
was able to determine that the suspect function is proctree but I
wasn't able to get it to dump and investigate further.  My knowledge
of debugging is almost non existant, any help on the matter would
be appreciated.  This has been happening since I updated around
the first week of October.
