After many hours, runned tests and crawling in ASL code - I still could not find anything particular... But finally got it working. I have found some notifications about disabling USB 3.0 in some cases in previous kernels helped to solve some case. I had thought - why not to disable all devices.. And then step by step - I tried all possible settings in BIOS...
It probably wasn't BIOS implementation. Disabling support for VT-D in BIOS - solved the case. @HwRhymes - can you confirm this? But it still sounds like possible bug in the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760842 Title: Natty Narwhal/Sandy Bridge Suspend Fails -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
