[Bug 145377] Re: Powertop reports huge number of wakeups and drains battery

[Colin King]

Hi Jean-Baptiste,

The power at bughost issue was in fact related to bug 177895, which turned
out to be a few issues, one of which was Opera killing the laptop with
excessive amounts of wakeups.. it's quite a drawn out saga.  As for the
WikiPage, it was originally written on the back of addressing bug
177895, so it's not entirely applicable for all cases, I just thought it
may be pulling a reference into this bug report just incase it helped. I
will review the WikiPage in respect to this bug and try and make it more
usable.

I suggest booting with the noapic kernel option and doing:

(cat /proc/interrupts; sleep 10; cat /proc/interrupts) > interrupts.log

and then using the dualcore.awk awk script (attached much earlier in the
bug report), and do the following:

awk -f dualcore.awk < interrupts.log > irq_delta.log

And repeat this with the normal kernel boot (without the noapic option).
Attach the results and I will see if there is anything we can do to
check the IRQ routing.

Colin
