Btw (may or may not be relevant): after the above experiment I have rebooted the machine in "Safe mode" (generic kernel, EARLY_AP_STARTUP enabled by default) - and spent some time doing non-intensive interactive work on this host (web browsing, editor, shell, all under KDE) - and after about an hour the machine froze: clock display not updating, keyboard unresponsive, console virtual terminals inaccessible) - so had to reboot. According to fans speed the machine was idle. The /var/log/messages does not show anything of interest before the freeze. All disks are under ZFS. Can EARLY_AP_STARTUP have an effect also _after_ booting? This host never hung during normal work when EARLY_AP_STARTUP was disabled (or with 11.0 and earlier). Mark
