>How about some more info- what was the machine check code?

Good point; Here's what I got:

unexpected machine check

    mces    = 0x1
    vector  = 0x670
    param   = 0xfffffc0000006048
    pc      = 0x12000b71c
    ra      = 0x12000b964
    curproc = 0xfffffe004a575000
	pid = 56, comm = gzip

panic: machine check

I didn't see anything else of note.
