Since live_workarounds poke around the w/a registers and checks to see if they survive across a reset, we are prone to fouling the machine and leaving it in a non-recoverable state. Wrap the probe inside a timeout to abort the test if the reset fails. v2: Include GEM_TRACE on declaring wedged. v3: Add a few includes to make the header look standalone.
