Title: Fix random HuC/GuC initialization failure of Intel i915 driver Status in HWE Next: New Status in linux package in Ubuntu: New Status in linux-oem package in Ubuntu: New Status in linux-oem-6.5 package in Ubuntu: New Status in linux source package in Jammy: New Status in linux-oem source package in Jammy: Invalid Status in linux-oem-6.5 source package in Jammy: In Progress Status in linux source package in Noble: New Status in linux-oem source package in Noble: New Status in linux-oem-6.5 source package in Noble: New Bug description: [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.
