I wouldn't say that no one is interested in helping. (And I think you've received a few more suggestions than your other recent message to freebsd-developers suggests.) For my part, I find it a bit difficult to track the status of your interrupt problem, and the interactivity problem, which may or may not be related. --Have you ruled out any contribution from overheating, like I think you were experiencing before with this machine? At one point, you were following some of mav@'s suggestions for power-saving, but then you posted a configuration that suggested that you had abandoned some of these settings and returned to the defaults. So are you running hot, or being throttled now? Have you tried running at a kern.hz < 1000, with throttling disabled, to see if that ameliorates the problem? --What graphics driver are you using? You were using x11/nvidia-driver, but then after the kib@ and alc@'s vm changes that led to problems with that driver, I thought you were using x11-drivers/xf86-video-nv -- is that still the case? Does switching drivers seem to influence the frequency or severity of the problems? --When do you experience these problems? Do they ever occur when you are _not_ running X? Have you tried temporarily disabling your usb and network devices, to see if they are contributing to the problem? Are you able to watch flash videos from local media, as opposed to those from a remote site, without problems? --Did you follow mav@'s suggestion to use something other than your hpet for the eventcounter and timecounter? The possible use of the hpet is one of the main differences between the new and old timing code, and you reported some problems with your hpet earlier. --Did you follow attilio@'s suggestion to obtain scheduling traces for the interactivity problem, as described in src/tools/sched/schedgraph.py? b.
