Hello
after updating to kernel-3.3.1-3.fc16.x86_64 i have too many interrupts.
My cpu is basically never idle.
Output of powertop:
Overview:
The battery reports a discharge rate of 16.9 W

I cant toggle the Power Saving state to 'Good'.

This Problem is not new and i could always solve it by compiling the Broadcom driver using source from:
http://www.broadcom.com/support/802.11/linux_sta.php
But this time it didn't help and so i tried it with b43-fwcutter, using the firmware from:
mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
Both drivers work well in the sense of a stable connection, but both have the interrupt problem.
My normal idle power consumption is about 8W and now it is about 16W.
My System:
Lenovo Ideapad U350
Pentium SU4100 2x 1.30GHz
Intel GMA X4500HD (IGP) shared memory
Network:
Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
Ethernet controller: Broadcom Corporation NetLink BCM57780 Gigabit Ethernet PCIe (rev 01)
I also tried different boot options:
acpi=off
acpi=force
pci=noacpi
pci=acpi
noapic
acpi_irq_nobalance
pcie_aspm=force
None of the options helped and with some i couldn't boot.
It would be great if anyone could help me.
Thanks.
