--- Comment #6 from Daniel Vetter <daniel at ffwll.ch> ---
[ 4483.626048] Kernel panic - not syncing: Timeout synchronizing machine check
over CPUs
[ 4484.664475] Shutting down cpus with NMI

That's a fatal mce, which is either busted hw or broken bios. It's not pretty
that the i915 panic handler then kills the box, but fixing that is much larger
problem (and atm not at the top).

The underlying MCE issue which kills the machine otoh is plain hw issues, so
closing as invalid. I guess you need to decomission/replace this machine if a
bios upgrade doesn't fix this.
