This shows the last commit from March 14: john@laptop15:~/git/kernel> git -P log -1 commit 4909d30a5b78240d282801fd2fb84a32f59f9e8a (HEAD -> SLE15-SP4, origin/SLE15-SP4) Author: Tony Jones <tonyj@suse.de> Date: Tue Mar 14 12:17:28 2023 -0700 perf/x86/uncore: Don't WARN_ON_ONCE() for a broken discovery table (bsc#1206824, bsc#1206493, bsc#1206492). suse-commit: 23fd14b823e378dfb3e61305633ee67c17881afa I was able to fix the issue by applying patch #1 that I mentioned in #c34.
