Re: High interrupt load using 5.8 Release GENERIC i386 on Acer Aspire 3630 laptop
Many thanks for the suggestions on executing acpidump and building the kernel with ACPI_DEBUG enabled. Regrettably, I presently don't have access to the Acer Aspire 3630 so it will take a few weeks to post an update on this. I'll make sure to follow up at the next opportunity. Kind regards, Peter

Thanks for the information. After some trial-and-error, I was able to
get a normal-looking interrupt load and a more responsive system by
simultaneously disabling acpi and cbb. Presently, I note a mem address
conflict which appears in the new dmesg output. However, the system is
running stably so far.
(If it's any help to report; I also tried a) setting
kern.timecounter.choice=i8254 and disabling cbb b) disabling acpi but
not cbb c) disabling the drivers loaded as children of cbb and acpi in
the driver hierarchy.)

High interrupt load using 5.8 Release GENERIC i386 on Acer Aspire 3630 laptop
Hi,
I have installed 5.8 Release GENERIC i386 on an Acer Aspire 3630
laptop. Even when the system is almost completely idle, `top'
consistently reports an interrupt load in the range 75%--80%.
Admittedly this hardware is more than 8 years old, nevertheless I
believe the load is unusually high, based on limited experience with
installing the same version of OpenBSD on a lower-spec i586 machine.
Is it possible that CPU cycles are being wasted due to the system
being mis-configured? If so, does anyone have any suggestions on how
to reduce the observed load?
