[ale] nforce smbus: error probing SMB1 and SMB2

[Greg Clifton]

Hello Joshua,

I second the motion of contacting ASUS, I have found them to be pretty
responsive to any technical queries. Perhaps they have a beta or custom BIOS
that would solve the problem.

I have a relatively new system at home with a single core Athlon 64 and a
Nvidia graphics card running the latest Ubuntu 64bit w/ 4GB of RAM that also
won't hibernate; system acts like it is going to sleep and then just
reboots. I forget the exact make/model, MSI or something cheaper ($50 for
mobo & CPU @ Frys a year or so ago) so I think the ACPI/AIPC issues are not
restricted to just ASUS mobos.
