Comment 53 for bug 575296

I see these entries in kern.log:

Jan 17 07:41:02 ion kernel: [ 2.604867] udev: starting version 151
Jan 17 07:41:02 ion kernel: [ 2.941637] i2c i2c-0: nForce2 SMBus adapter at 0x4d00
Jan 17 07:41:02 ion kernel: [ 2.941655] ACPI: resource nForce2_smbus [0x4e00-0x4e3f] conflicts with ACPI region SM00 [0x4e00-0x4e3f]
Jan 17 07:41:02 ion kernel: [ 2.941663] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
Jan 17 07:41:02 ion kernel: [ 2.941671] nForce2_smbus 0000:00:03.2: Error probing SMB2.
Jan 17 07:41:02 ion kernel: [ 2.944484] lp: driver loaded but no devices found

The "...Error probing SMB2" message appears during boot with a long pause.

The system is Zotac ionitx-a-u atom n330 based.

uname -a says:
Linux ion 2.6.32-27-generic-pae #49-Ubuntu SMP Thu Dec 2 00:07:52 UTC 2010 i686 GNU/Linux

Also kernel tainting nvidia driver:
NVIDIA UNIX x86 Kernel Module 195.36.24

Since these issues seem to be hardware monitoring related, I wonder if the proprietary nvidia driver is a common theme as there is a temperature readout in the application System -> Administration -> Nvidia X Server Settings under GPU xxx -> Thermal Settings. Maybe this application is fighting over the hardware sensors?
