[Kernel-packages] [Bug 1939347] Re: Ubuntu 20.04 freeze since kernel 5.11
I recently hit this issue after installing Ubuntu 22.04.2 to Dell Latitude 7490 laptop and updated everything (kernel 5.19.0-41-generic now). I first tried with "options i915 enable_psr=0" in /etc/modprobe.d/i915.conf, but that only delayed the freeze. Then adding also "enable_dc=0" seems to make system stable. So full line in /etc/modprobe.d/i915.conf that works for me is "options i915 enable_psr=0 enable_dc=0". -- 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/1939347 Title: Ubuntu 20.04 freeze since kernel 5.11 Status in linux package in Ubuntu: Won't Fix Bug description: Since the last kernel update 5.11.0-25-generic, the system freezes in a few seconds or minutes, sometimes even on the login screen. The machine is a recent dell latitude 7490. The graphics card is Intel Corporation UHD Graphics 620 (rev 07). No multiboot. No problem with the previous kernel 5.8.0-63. I had the same problem with fedora a few months ago, which forced me to switch to ubuntu without any problems so far.
