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.

The problem is described here: https://gitlab.freedesktop.org/drm/amd/-/issues/3347
