Moreover, CPU idle time data look really weird. Neither tweaking kern.timecounter.hardware nor disabling ACPI seems to affect that. The respective lines in the output from "top -S" reads: 11 root 171 52 0K 8K RUN 4:10 130.18% 130.18% idle 28 root -32 -151 0K 8K *Giant 0:09 31.15% 31.15% swi4: clock sio Were there any attempts to investigate this singularity? -- Yar
