The last working version is 6.8.0-49.49, however, 6.8 line symptoms are as on my other bug 2093268 - there's picture, very laggy and high utilisation of kworker thread. On 6.11 line the image on main screen is gone.
In both second 4K HDMI screen works, with little lags to interaction with Gnome elements. In both cases errors in dmesg have some similarities. I can try test limited number of 6.11 versions, but as this takes 12h to manifest and impacts my day to day work, this cannot be plenty. I'm using Mozilla's Deb Firefox and snap VS Code intensively. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-meta-lowlatency-hwe-6.11 in Ubuntu. https://bugs.launchpad.net/bugs/2098670 Title: amdgpu: No picture on main screen after wake up Status in linux-meta-lowlatency-hwe-6.11 package in Ubuntu: Confirmed Bug description: So far looks like any kernel after 6.8.0-49.49 has some bugs related to amdgpu and wakes. I tried HWE 6.11 hoping that would have enough bugfixes from upstream to get me sorted, but it's even worse than #2093268 as the screen is blank after unlock.
