I test the test kernel built by Koba, https://drive.google.com/drive/folders/10ns_2dnmPRf091L3LABpIh680kStvTk4?usp=sharing
sku: FPA-DVT2-C6 BIOS: 0.0.26 It still have the error in kernel, but the screen can show successfully. I tried pure 5.14.0-1011-oem, the issue is still reproduced. Therefore, I think the patch set indeed fix something, but it won't get rid off "kernel: i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun: soft,transcoder," however, my local build drmtip [1] can eliminate the error message.

Currently, we have some problem on other platform STRADL-DVT2-C4/C5B, it will cause it failed to suspend/resume. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1954728 Title: Fix No Screen after login to Desktop on sku with 3840x2400 panel To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1954728/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
