[Bug 537396] Re: events/0 spikes CPU every 3 seconds since upgrade to 2.6.31-20

[Charlie DeTar]

Pardon my earlier confusion.  Of course, the 3945ABG is a wireless lan
card, and the problematic device in this ticket is the wired LAN card.
The correct device is:

00:19.0 Ethernet controller [0200]: Intel Corporation 82566MM Gigabit Network Connection [8086:1049] (rev 03)
	Subsystem: Lenovo Device [17aa:20de]
	Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx+
	Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
	Latency: 0
	Interrupt: pin A routed to IRQ 27
	Region 0: Memory at fe000000 (32-bit, non-prefetchable) [size=128K]
	Region 1: Memory at fe025000 (32-bit, non-prefetchable) [size=4K]
	Region 2: I/O ports at 1840 [size=32]
	Capabilities: <access denied>
	Kernel driver in use: e1000e
	Kernel modules: e1000e

The difficulty seems to be arising from the e1000e module.  In addition
to disabling eth0 with ``ifconfig eth0 down``, the CPU spikes can be
stopped by removing the e1000e module with ``modprobe -r e1000e``.

Wired LAN does not currently function, and the hardware LEDs are
constantly lit.
