Hello, finally bit the bullet and upgraded my Dell D810 to RELENG_6 from latest 5. All seemed to go well but certain things are slow/odd. X startup is slow but once running everything seems mostly ok. Rebuilding ports and they seem to be rebuilding ok. On shutdown the sync operation takes far longer and get vnodes remaining numbers like 77777777777777777777777777777777777777774444444444444444433444 44422222222222222222122222211111111111000000000000000000000000 0000000 which is really odd. The second hand on emiclock jumps typically in intervals of 5 or more seconds. If I run somnething like "find /" then the second hand clicks over smoothly in 1s jumps. Unplugging and replugging in usb mouse takes a while for it to be recognized. Again if system is busy then it gets recognized quickly. I added kern.hz="100" to loader.conf but still the same behaviour. It feels like some sort of interrupt problem but vmstat looks ok except I'd expect that cpu0 would have a rate of 100??? vmstat -i interrupt total rate irq1: atkbd0 3777 2 irq9: acpi0 1 0 irq12: psm0 2070 1 irq13: npx0 1 0 irq14: ata0 10642 6 irq15: ata1 41 0 irq16: pcm0 bge0++ 1828 1 irq18: uhci2 20771 13 cpu0: timer 65570 41 Total 104701 66 This is a generic kernel, no weird make.conf vars. Some sort of ACPI problem??? Any suggestions? thanks -- tonym
