Comment 87 for bug 1201528

The 3.12-rc4 kernel is now out. Can you first test this kernel, to see if the bug was already fixed upstream:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-rc4-saucy/

If the bug still exists in v3.12-rc4, then we should continue bisecting. Per comment #80, 3.9-rc4 exhibits the bug. Can you also test the following kernel:

v3.9-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc2-raring/
v3.9-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc3-raring/
