That's not the latest mainline kernel. Hence, upstream doesn't care about your issue unless it's reproducible in their (not Ubuntu's) kernel. Also, this is not currently considered Status Triaged as outlined in https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Triaged_Bugs .

I haven't found a pattern on this but I think it happens on the following sequence: 1 - Suspend the computer while connected to power cord 2 - Disconnect from power and resume system running on battery 3 - Suspend the system (still on battery) 4 - Connect power cord, resume system and fan will not work As I said I haven't found a pattern, but i THINK this is sequence of events that leads to fan failure.
