I'm thinking this is not a coincidence. I was running 2.6.22.5, and 
looking at your problems, I just had a similar experience on tuesday.. 
The network was still fine after kernel errors so that I was able to 
login with SSH. See:

With ata_piix Intel SATA I got these errors:

ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen

If this is the same error, then the problem is not ata_piix/nvidia 
specific since you seem to have an nvidia SATA controller.
