Hi, When booting I observe an additional 30-second delay after this print: > Timecounters tick every 1.000 msec ~30 second delay and boot continues like normal. Checking "vmstat -i" reveals that some timers have been running loose. > cpu0:timer 44300 442 > cpu1:timer 40561 404 > cpu3:timer 48462822 483058 > cpu2:timer 48477898 483209 Trying to add delays and/or prints around the Timecounters printout makes the issue go away. Any ideas for debugging? Looks like a startup race to me. --HPS
