I'm getting similar errors in an Atom powered DIY machine w/4 cores.
2GB RAM with a 1TB hdd. (I used to have 2 TB but removed 1 drive when
the errors were compounded):
[58854.080065] ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen

[58893.980632] ata4.00: device reported invalid CHS sector 0
[58893.980655] ata4: EH complete
Seems like a power to the drive issue when the machine is kind of idle
for a while. It isn't a notebook computer, but maybe Ubuntu thinks it
is because of the Atom processor? What other information can I provide
to help troubleshoot?
