    That did it. 

    I think I've figured it out.  The floating point exception is installed
    as a trap-gate, which leaves interrupts enabled.  If an interrupt occurs
    just as the FP exception occurs it can change the state of the FPU
    and confuse npx_intr().
    Try this patch out and tell me if you still get the panic.  It isn't 
    the 'real' fix, but it will tell us if that is the problem.  The
    crash does not seem to occur with the patch.

    The real fix is going to be simply to make npx_intr() and npxdna()
    handle each other's cases as well as their own, and then get rid of
    the assertion.  I think I also need to have them go into a critical 
    section.

Yea,

it seems to no longer panic here either. I have it running for ~15 
minutes now.
