Comment 4 for bug 394826

Ok, It seems your issue might be driver related and so I don't think I can help you any more. I'll reset the bug status to new so that somebody else can take over the triaging.

As for the load cycles in ubuntu:
Laptop Mode is DISABLED BY DEFAULT in Ubuntu, So if somebody has an issue like that it's because that enabled laptop_mode themselves. Also note that laptop_mode should only be invoked while on battery power where the spin down of a hard drive can improve battery life.

It would also help if you could please include the following additional information (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.

Thank you in advance.
