Hello Christopher, I saw the mapping of Ubuntu kernels to upstream kernel, but couldn't find Ubuntu kernel 3.13.0-30.54. So, I tested assuming Ubuntu 3.13.0-29.52 is the current kernel, which is v3.13.11.2 in upstream
I got that the bug is first fixed in v3.14-rc1-trusty. I cannot go further with commit by commit reverse bisecting, as I don't have that much time and confidence. Sorry for that. Still, I would like if I can help fixing this bug in some other way(easier way :P) Thanks -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1335795 Title: [Asus K55VM] It does not suspend after upgrading to 14.04 Status in “linux” package in Ubuntu: Incomplete Bug description: I recently upgraded to Ubuntu 14.04 from 13.10 After that my laptop does not suspend.
