    MCU1 crashes - bad MX day

    This morning, I was greeted with a completely blank, dead MCU1. It had been working fine but sluggish yesterday, but two-scroll-wheel reboots have been taking more than two minutes before today. I tried the reboot this morning, gave it three minutes and gave up. The vehicle took 1-2 minutes...
