It did not help the debugging, though. The quick flashing of the error message and instant reboot still prevent reading the message. Anyhow I managed to notice that autoconfigure got past reporting atapci0 and atapci1. Right after these there has usually been notes about timecounter, etc. So, I got the idea that maybe it is the timecounter initialization that fails. This could also explain why there is no delay between the error message and reboot. Testing this hypothesis is now on my to do list, but it will take some time. --jau
