Seen during boot the last few days on my laptop:

running 3.0.0-rc4-mmotm0622:
Jul 2 13:08:37 turing-police kernel: [ 2.788108] hub 2-0:1.0: over-current condition on port 1
Jul 2 13:08:37 turing-police kernel: [ 2.990088] hub 2-0:1.0: over-current condition on port 2
Jul 2 13:08:37 turing-police kernel: [ 3.193073] hub 6-0:1.0: over-current condition on port 1
Jul 2 13:08:37 turing-police kernel: [ 3.395088] hub 6-0:1.0: over-current condition on port 2

running 3.0.0-rc5-mmotm0630:
Jul 5 09:43:36 turing-police kernel: [ 203.686082] hub 6-0:1.0: over-current condition on port 1
Jul 5 09:43:36 turing-police kernel: [ 203.969179] hub 6-0:1.0: over-current condition on port 2
Jul 5 09:43:36 turing-police kernel: [ 204.217077] hub 6-0:1.0: over-current condition on port 1

The problem? I don't see any devices that would *cause* the condition:

# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 005 Device 002: ID 0a5c:5800 Broadcom Corp. BCM5880 Secure Applications Processor
Bus 001 Device 005: ID 045e:0023 Microsoft Corp. Trackball Optical
Bus 001 Device 006: ID 0e8f:0020 GreenAsia Inc. USB to PS/2 Adapter

The device 5 and 6 on bus 1 are attached to the docking station, the Jul 2 boot
was undocked and those two devices weren't present. Nobody home on bus 2 or 6
at any time, as far as I can tell.

Any ideas?
