Hi, I wonder if anybody has an idea what can cause lot of "calcru: runtime went backwards" when running 6.0-CURRENT under VmWare 5.0. I do not see any visible problems with this, but it is just quite annoying. My timecounter-related oids look like the following: kern.timecounter.stepwarnings: 0 kern.timecounter.nbinuptime: 27463623 kern.timecounter.nnanouptime: 0 kern.timecounter.nmicrouptime: 6261 kern.timecounter.nbintime: 2783660 kern.timecounter.nnanotime: 1086 kern.timecounter.nmicrotime: 2782573 kern.timecounter.ngetbinuptime: 15989 kern.timecounter.ngetnanouptime: 2834 kern.timecounter.ngetmicrouptime: 3417463 kern.timecounter.ngetbintime: 0 kern.timecounter.ngetnanotime: 1 kern.timecounter.ngetmicrotime: 6645 kern.timecounter.nsetclock: 5 kern.timecounter.hardware: ACPI-safe kern.timecounter.choice: TSC(800) ACPI-safe(1000) i8254(0) dummy(-1000000) kern.timecounter.tick: 1 Regards, Maxim calcru: runtime went backwards from 16430817 usec to 16430811 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 17253868 usec to 17253844 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 45697023 usec to 45697017 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 72251267 usec to 72251261 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 74393888 usec to 74393882 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 75331894 usec to 75331884 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 81173048 usec to 81173046 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 83591856 usec to 83591850 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 85953778 usec to 85953772 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 129215402 usec to 129215396 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 130114935 usec to 130114930 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 175756138 usec to 175756132 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 177168820 usec to 177168814 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 189821362 usec to 189821327 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 191069009 usec to 191069003 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 191207231 usec to 191207225 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 195724967 usec to 195724960 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 219595821 usec to 219595815 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 222284948 usec to 222284942 usec for pid 592 (vmware-guestd) calcru: runtime went backwards from 223661139 usec to 223661133 usec for pid 592 (vmware-guestd)
