Firstly, there are no differences in my good and bad lspci outputs :(.
Secondly, what Kelly observes might still be ok - about 2500
interrupts per second. When I use my wireless connection to download
at say 1 or 2 MB/s, I do get about 4000 interrupts per second. And
these 4000 are not 'phantom' interrupts as I do see usb and ipw3945
come up in the top of the list accounting for most of those 4000. In
the second case when I see 22k per second, there is nothing that shows
up - its in fact the same as when its at 150 per second. So Kelly,
when you get 2500 interrupts per second are these 'phantom' like in my
bad state, or is there something in the powertop list that accounts
for these.
Thanks,
Hirakendu.
The extra wakeups are 'phantoms'.
Well I thought I was having better results after a reboot but that
proved not to be true. I just rebooted and I've got 22000 wakeups/sec.
What's next? I did get a message in dmesg that's interesting. I'm not
sure if this message shows up every time, maybe it's part of the problem.
from dmesg:
hpet_resources: 0xfed00000 is busy
