https://bugzilla.suse.com/show_bug.cgi?id=1233134 Bug ID: 1233134 Summary: boot freeze with kernel-default=5.14.21-150500.55.86 and amdgpu Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: x86-64 OS: Other Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: heiko.rommel@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- After having installed version 5.14.21-150500.55.86 of the kernel release candidate for SLE 15 SP5 / openSUSE 15.5 on my desktop, the system hangs in early boot with no video signal. When booting with loglevel=7 and drm.debug=0x1e I see that there are apparently some errors in drm, but they are only displayed for a very short time (< 1 sec) and then the signal to the display is cut off. The GPU is a discrete AMD Radeon RX 7800 XT. What did work: a) booting with nomodeset b) creating an update directory in /lib/modules/ for the new kernel and putting there the amdgpu.ko.zst from the previous kernel, rebuilding the initrd and booting (see https://bugzilla.suse.com/show_bug.cgi?id=1215802#c11) This looks like an re-incarnation of https://bugzilla.suse.com/show_bug.cgi?id=1215802 reported 14 month ago, but maybe with different root problems. Currently, I am trying to get a legible video of the booting. -- You are receiving this mail because: You are on the CC list for the bug.
