There are more kernels available here: http://koji.fedoraproject.org/koji/packageinfo?packageID=8 You should also try kernel-4.4.4-300.fc23 and kernel-4.4.4-301.fc23 to best find the point of regression. Then please file a bug into bugzilla against kernel, and describe your problem. If you have localized your issue well between two minor updates, there's a high chance the kernel team can find the regression and fix it (also feel free to poke someone at #fedora-kernel if you see no feedback on that bug report). However, I have to say that I also have X220 at home, I tested it with kernel 4.4.5-300 and found no issues with suspend. Your hardware doesn't have to be exactly the same as mine, though. It just means that not all X220 laptops are affected. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
