Hello everyone, having upgraded my laptop to a recent 8_RELENG from an earlier 8_RELENG from the time of the 8.0 release, I find it behaves very strangely. When booting devd hangs often until cancelled with ctrl+c. Sometimes it seems that pending work is waiting for disk activity until it is kicked off. I noticed this when setting up the keycodes for zsh and the duration for reading each key differed significantly depending whether there was disk activity or not. This happens as well in X as in console. I tried disabling powerd, setting kern.hz to 100 and using the timers ACPI- FAST (default), HPET, i8254 and TSC - no change so far. I am not sure if it is because an ancient configuration setting I had in place earlier and that I am missing now or whether this is due to a code change. However, I am at a loss and would appreciate further input on the matter. Due to the upcoming release I am posting to -stable just to get this tracked in case this is the symptom of some obscure bug. Thank you in advance & Regards Christof This is vmstat -i: % vmstat -i ~ interrupt total rate irq1: atkbd0 28 0 irq9: acpi0 173 0 irq12: psm0 17 0 irq14: ata0 3009 8 irq16: wpi0 uhci3+ 5516 15 irq18: uhci2 14 0 irq21: fwohci0 2 0 irq22: bfe0 sdhci0 608 1 irq23: uhci0 ehci0 2 0 cpu0: timer 18165 51 irq256: hdac0 17 0 cpu1: timer 17986 50 Total 45537 127 this is dmesg: % dmesg ~ Copyright (c) 1992-2010 The FreeBSD Project.
