RE: Panic with latest sources.

:Ok here we go...
:Regression report (GENERIC kernel):

:2) 2004.02.08.00.00.00 - works

:So...something committed (and which still exists) between 2004.02.10.06.00.00
:and 2004.02.10.12.00.00 results in the following sort of early panic.

    All right, lets see.  Not a whole lot changed between those dates.

    Try undoing some of these recent changes, one at a time, and see if it
    fixes the problem:

    The double psm reset:

    I also updated the token code but that would have crashed in a 
    different place, and I updated a few malloc() calls in the NFS
    code which should not have been touched that early in the boot 
    sequence.

    Make sure you do complete kernel builds (do not use -DNOCLEAN)
    when testing.
