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.

ok interesting; there are 2 differences in the 2 files, the most
important one being the PME- -> PME+ change. I wonder if Linux isn't
doing something it should be doing; I'll investigate this more
tomorrow when it's a more reasonable hour..
