Some of the software on the device is run by a software lifeguard that
either reboots the device when the software crashes, or tries to respawn
it a certain number of times, then reboots the device if this fails.

So my guess is that something causes one of those to crash.
Examples of software that run with this kind of policy is the X-server,
bme, mce, and the dsp software.

The problem is that tracking down this kind of bugs is extremely tricky
unless you can somehow come up with a reproducible way of triggering the
bug (even if it takes 10 days the bug can still be located with the
proper tools if there's a reproducible way to trigger it).

So any further input is *warmly* accepted.
