Moreover, it seems like A1 computer have 92% of all zeroes: 18989 send_sync 0 0 0 0 1557 send_sync 0 0 0 1 At the same time, A2 computer have only 54% of all zeroes: 11498 send_sync 0 0 0 0 9621 send_sync 0 0 0 1 I have found the difference in config: A1 root@fspa1:~/clock/new_res # cat /boot/loader.conf boot_verbose=3D"YES" coretemp_load=3D"YES" autoboot_delay=3D"-1" loader_logo=3D"fbsdbw" kern.ipc.semmns=3D350 hw.em.txd=3D"4096" hw.em.rxd=3D"4096" hw.em.rx_process_limit=3D"-1" hw.em.enable_msix=3D"0" A2 root@fspa2:~/clock/new_res # cat /boot/loader.conf console=3D"comconsole,vidconsole" coretemp_load=3D"YES" autoboot_delay=3D"-1" loader_logo=3D"fbsdbw" kern.ipc.semmns=3D"350" hw.em.txd=3D"4096" hw.em.rxd=3D"4096" hw.em.rx_process_limit=3D"-1" hw.em.enable_msix=3D"0" Can boot_verbose=3D"YES" or console=3D"comconsole,vidconsole" make such dif= ference? --=20 You are receiving this mail because: You are the assignee for the bug.=
