Hi Chris (penalvch) Kernel 4.12rc1 and rc4 are both fine in terms of the bug and seem to run very smoothly, but the 4.11rc1, 4.11.1, 4.11.3 all show the bug (and I have seen them crash HARD, not just screen glitches).
I havent yet gone back through 4.10 yet to find the first 'bad' kernel. Can you confirm that the following Ubuntu kernels correlate to the upstream as follows? 4.10.0-22.24 is equivalent to 4.10.15 mainline 4.10.0-21.23 is equivalent to 4.10.11 mainline 4.10.0-19.21 is equivalent to 4.10.8 mainline Ubuntu -19 kernel is the first one i saw on my 17.04 install, which did show the bug. Where would you suggest going back to? I dont have any experience with git so am not sure I can dig deeper to find the bad commit, I'm afraid. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1695989 Title: i915 *ERROR* CPU pipe A FIFO underrun - graphic glitches To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1695989/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
