Hello, colleagues.
Commit f2d5dcb48f7ba9e3ff249d58fc1fa963d374e66a "bounds: support non-power-of-two CONFIG_NR_CPUS" (https://github.com/torvalds/linux/commit/f2d5dcb48f7ba9e3ff249d58fc1fa963d37...) was backported to 6.1.x-stable (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...), but causes a serious regression on quite a lot of hardware with AMD GPUs, kernel panics.
It was backported to 6.1.84, 6.1.84 has problems, 6/1/83 does not, the newest 6.1.88 still has this problem.
Does v6.8.3 (which contains cf778fff03be) have this problem? How about current Linus master?
6.1.88 - has problem 6.6.27 - does not have problem 6.9-rc from commit efdfbbc4dcc8f98754056971f88af0f7ff906144 https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git - does not have problem
6.8.3 was not tested, but we can test it if needed.
What kernel config were you using? I don't see that info on https://linux-hardware.org/?probe=9c92ac1222 (maybe my tired eyes can't see it)
Kernel config for 6.1: https://abf.io/import/kernel-6.1/blob/bcb3e9611f/kernel-x86_64.config For 6.6: https://abf.io/import/kernel-6.6/blob/7404a4d3d5/kernel-x86_64.config 6.9-rc was built with copypastied config from 6.6 (https://abf.io/build_lists/5028240)
