hi, please try a recent vanilla kernel and see if it's reproducible. 2.6.29 would be a good choice. if the problem still exists in 2.6.29 kernel, please attach the output of dmesg and "grep . /sys/firmware/acpi/interrupts/*" after the interrupt storm occurs. please also attach the acpidump of this laptop. it would be great of you can open a new bug report at http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI and attach all the info there. thanks, rui On Mon, 2009-05-04 at 18:00 +0800, Christopher HORLER wrote: > Hello, > > I think I'm experiencing some kind of ACPI issue, I haven't been able > to identify a series of actions that causes this. > > I first noticed the problem when looking at 'top' - seeing kacpi at > the top of the process list (followed by kacpi_notify). > I have powertop installed, the dump is attached - acpi interrupts seem > to be excessive. > > The computer is perhaps not the best machine: Arima M620-DC.
