After bootup I will see tons of calcru: negative time of -953757 usec for pid 636 (make) calcru: negative time of -820616 usec for pid 636 (make) microuptime() went backwards (1969.4485199 -> 1969.552693) microuptime() went backwards (1969.4485199 -> 1969.690311) messages, together with processes with a negative CPU usage time. Something is going wrong during setting clock interrupts. A "vmstat -i" shows (among other interrupts): clk irq0 79496 49 rtc irq8 101753 63 which is about half the rate it should be. The latest working kernel I was booting before was from Jul, 13th If I disable ACPI in the kernel the interrupt rate is back to normal. ACPI related boot messages: acpi0: on motherboard acpi0: power button is handled as a fixed feature programming model. acpi_timer0: <32-bit timer at 3.579545MHz> port 0x4008-0x400b on acpi0 acpi_cpu0: on acpi0 acpi_button0: on acpi0 acpi_pcib0: on acpi0 pci0: on acpi_pcib0 acpi_cpu0: set speed to 100.0% acpi_cpu: CPU throttling enabled, 2 steps from 100% to 50.0% Mainboard is a GigaByte GA-5AX with F3 BIOS. I will provide further configuration information if needed. -- Daniel To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
