[Kernel-packages] [Bug 1924624] Re: After upgrade to 5.8.0-49/5.8.0-50 with Intel graphics (Gen7: Haswell/Ivy Bridge) a lot of glitches render screen unusable
5.8.0-52 in proposed works for me. Thanks! But why wait more than 2 weeks to resolve it? Thousands of computers are directly impacted and unusable and not everyone know how they can change his kernel version on boot. Only around me, 4 people are impacted and also myself on 2 computers. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1924624 Title: After upgrade to 5.8.0-49/5.8.0-50 with Intel graphics (Gen7: Haswell/Ivy Bridge) a lot of glitches render screen unusable Status in linux package in Ubuntu: Confirmed Status in linux-meta-hwe-5.8 package in Ubuntu: Confirmed Bug description: After upgrading to 5.8.0-49, on a laprtop with intel graphics, graphics was suddenly extremely glitchy.

@Joseph Salisbury (jsalisbury) I installed your patched kernel on my Desktop today and it run now from 3 hours without problem, no more cifs flood.. :) So, i will continue my test today, but apparently this bug is fixed in your patched kernel. If is confirmed, can you tell me approximatively when this kernel will appear in the main ubuntu repository?
