[Bug 1883681] Re: System freezes on specific kernel
Hi Anand, Yes, that patch is available since 4.4.0-185.215. Please note that this version if for the linux-image-4.4.0-185-generic package. You mentioned version numbers for the linux-generic meta package (which pulls in linux-image--generic package as a dependency.) Either way, the first number (-185, -186, etc) match between both packages. If you're on -186 the fix should be available since it's present since -185. cheers, Mauricio -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883681 Title: System freezes on specific kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1883681/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
