commit 34098b71fa1b365ffb0c12fb84ebb7aa26c8f300
Author: Chris Wilson <chris@chris-wilson.co.uk>

    lib/igt_gt: Handle SIGINT whilst writing to i915_error_state
    
    Becareful in case we try and eat the error state whilst interrupts are
    being sent and repeat the write() until we finish uninterrupted.
