<pre>
The following test is failing for me on 6.1.1 kernel. After booting 6.0.14, it passes. Tested as of dfc20708bcdf7b4c4bea8595fc4ac8674634d5e6, on Gentoo Linux/amd64.
Kernel config for 6.0.14: [config-6.0.14.txt](https://github.com/llvm/llvm-project/files/10307840/config-6.0.14.txt)
Kernel config for 6.1.1: [config-6.1.1.txt](https://github.com/llvm/llvm-project/files/10307841/config-6.1.1.txt)
Let me know if there's anything else that could help.
