Also, with ACPI-safe timecounter there are a lot of messages like: Jul 4 14:37:34 kernel: calcru: negative runtime of -7736790 usec for pid 12 (swi4: clock sio) Jul 4 14:37:34 kernel: calcru: negative runtime of -509284 usec for pid 516 (sshd) Jul 4 14:37:34 kernel: calcru: negative runtime of -624737 usec for pid 421 (ntpd) Jul 4 14:37:34 kernel: calcru: negative runtime of -1315926 usec for pid 44 (softdepflush) Jul 4 14:37:34 kernel: calcru: negative runtime of -1018507 usec for pid 32 (irq14: ata0) Jul 4 14:37:34 kernel: calcru: negative runtime of -1012373 usec for pid 21 (irq16: em0 uhci3) Jul 4 14:37:34 kernel: calcru: runtime went backwards from 516063 usec to 216547 usec for pid 3 (g_up) Jul 4 14:37:34 kernel: calcru: negative runtime of -7736785 usec for pid 12 (swi4: clock sio) Jul 4 14:37:34 kernel: calcru: negative runtime of -509284 usec for pid 516 (sshd) Jul 4 14:37:34 kernel: calcru: negative runtime of -624737 usec for pid 421 (ntpd) Jul 4 14:37:34 kernel: calcru: negative runtime of -1315926 usec for pid 44 (softdepflush) On FreeBSD 7-CURRENT everything is OK, no problems with clock with any of ACPI-safe, TSC or i8254 timecounters. ps. I can provide full access to the server, if somebody could resolve the problem. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
