These workarounds don't work for me. What does work though is keeping CPU loaded (at least one core) with something like "md5</dev/zero" in the background. Some timings are still of, especially with TSC timecounter, but with i8254 and ACPI-fast it's mostly all right. Just constantly moving mouse (touchpad) in X also helps. > Some symptoms: Very same symptoms. Word for word (but I didn't run ddb). My dmesg and sysctl from 6.x and 7.x are at: http://people.freebsd.org/~sat/abc/dj/ This laptop basically has ATI RS 485MC chipset + SB460 south bridge. What may be of intereset is that VMware guest hosts have rather similar issues until you disable apic.
