It depends on the crash.  In my case, hardware flipped bits randomly
under high load, eventually leading to a kernel crash.  This is hard
to correct in software.  Generally, it's better to fix the broken
hardware.

I haven't lost data due to simple crashes yet (power outages,
crash-early kernel bugs, or MCEs because of thermal issues -- knock on
wood).
