Public bug reported: [Impact] i915 error can sometimes be found in kernel message when booting the machine w/ power unplugged kernel: i915 0000:00:02.0: [drm] *ERROR* GT1: GuC initialization failed -EIO kernel: i915 0000:00:02.0: [drm] *ERROR* GT1: Enabling uc failed (-5) kernel: i915 0000:00:02.0: [drm] *ERROR* GT1: Failed to initialize GPU, declaring it wedged! The GPU won't work with this failure
[Fix] Backport the upatream fix for allowing slow HuC loading. [Test] 1. Unplug the power of the laptop and make sure it's charged by battery 2. Cold boot or Warm boot the machine and check the GuC init fail message. 3. Go to settings - > about --> graphics to make sure the GPU information is correct every boot. [Where problems could occur] Simply increase the loading time of HuC still get a working system. Should be low risk of regression. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux-oem (Ubuntu) Importance: Undecided Status: New ** Affects: linux-oem-6.5 (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Affects: linux-oem (Ubuntu Jammy) Importance: Undecided Status: Invalid ** Affects: linux-oem-6.5 (Ubuntu Jammy) Importance: Undecided Status: In Progress ** Affects: linux (Ubuntu Noble) Importance: Undecided Status: New ** Affects: linux-oem (Ubuntu Noble) Importance: Undecided Status: New ** Affects: linux-oem-6.5 (Ubuntu Noble) Importance: Undecided Status: New ** Tags: oem-priority originate-from-2051627 stella ** Also affects: linux-oem (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Noble) Importance: Undecided Status: New ** Also affects: linux-oem (Ubuntu Noble) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux-oem (Ubuntu Jammy) Importance: Undecided Status: New ** Changed in: linux-oem (Ubuntu Jammy) Status: New => In Progress ** Also affects: linux-oem-6.5 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-oem (Ubuntu Jammy) Status: In Progress => Invalid ** Changed in: linux-oem-6.5 (Ubuntu Jammy) Status: New => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2061049 Title: Fix random HuC/GuC initialization failure of Intel i915 driver To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2061049/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
