Ubuntu 14.04 (trusty) Kernel 3.13.0-44-generic HP laptop Compaq nx6325 A working suspend via Applications Menu/Log Out results in power switch green LED blinking on/off every few seconds. The laptop will do this the first time after a reboot but then every second attempt to suspend results in power switch green LED staying on. Screen goes black and have not found any key sequences that respond. The only option is to hold the power switch down for several seconds to do a hard reset. On restart it says... System program problem detected Report problem Clicked above several times, nothing happens, eventually pop up(s) go away. After this a dmesg doesn't seem to give clues - it does not even contain the word suspend for instance. Following the reboot the laptop will now suspend correctly once, wake up ok but then fail to suspend when asked the second time. What clues to search for to suspend everytime?

In short: Suspend only works once, the second attempt at a suspend results in the monitor going blank as it was entering suspend, but the computer still running, as evidenced by the hard drive and fans still running. The computer can then not be awaken anymore, only a hard reset and subsequent reboot returns the PC to working state. When I check for errors after the first suspend, I see the following errors in the log: Code: [ 8461.100062] ahci 0000:05:00.0: failed to stop engine (-5) [ 8461.600062] ahci 0000:05:00.0: failed to stop engine (-5) [ 8463.170076] ata9: failed to resume link (SControl FFFFFFFF) [ 8463.170109] ata10: failed to resume link (SControl FFFFFFFF) [ 8467.510109] ata9: failed to resume link (SControl FFFFFFFF) [ 8467.510163] ata10: failed to resume link (SControl FFFFFFFF) So it seems to me that it has something to do with AHCI. I searched for this error in the forum, but I could not find anything. I also tried various suggestions, such as using uswsusp and the hibernate scripts, and including ahci in the suspend module lust. But each of the result in the exact same behavior: First suspend works fine, second suspend fails and reset is necessary.
