Running vanilla 1.4 on an AlphaStations 600 5/333:

unexpected machine check:

    mces    = 0x1
    vector  = 0x670
    param   = 0xfffffc0000006060
    pc      = 0xfffffc0000300494
    ra      = 0xfffffc0000300540
    curproc = 0xfffffc0001483128
        pid = 122, comm = ypbind

panic: machine check

The PC is at XentInt. The return address is at XentSys+80.

Dunno how to repeat. Happened out of the blue.
