I decided to speed things up a little and continued the bisection on my own, compiling kernels on my machine directly.
The last good commit is 4a6c3031a7a34bfea80b84e9f657c1d07f21166a "mei: fix return value on disconnect timeout" The first bad commit is fe5c234e529ff6fc0b4a79c088a1a6d3878ad4e6 "USB: Fix persist resume of some SS USB devices" Looks like this patch that is trying to fix resuming SS USB devices is causing my SS USB devices to be dead after resume. -- 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/1384041 Title: [Dell Precision M3800] USB is dead after resume from sleep Status in “linux” package in Ubuntu: Confirmed Bug description: After resuming from sleep (suspend to ram), all external usb ports are dead. The laptop's built in keyboard and synaptic touch pad (I think it is vonnected via internal usb, but not 100% sure) still work. Only a complete power down and reboot seem to bring back the devices. The problem does not happen with the previous kernel 3.13.0-36.
