Mr. Christopher, I have different motheboard than you mentioned. My motherboard is without USB3 support, so it is GA-H61M-D2H, not GA-H61M-D2H-USB3. Plus, there are 2 revisions of my motherboard - rev 1.0 and rev 1.2. I own rev 1.0 for which the most recent BIOS is version F5 which I already had installed during testing and sending this bug report. The most recent BIOS for my motherboard can be found here - http://www.gigabyte.com/products/product-page.aspx?pid=4002#bios So the problem is present with the latest version of BIOS for my motherboard.
Output of sudo dmidecode -s bios-version && sudo dmidecode -s bios- release-date: F5 05/18/2012 I do not know if it is important to mention, but maybe it can be helpful, so I will mention it - I tested suspend with debian 7.7.0 which uses much older version of kernel and the problem is not present there - I was able to suspend PC approx. 20 times without problem. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags removed: bios-outdated-f6 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1412873 Title: Ubuntu 14.10 sometimes does not suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1412873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
