Vanilla Kernel 5.17.0 with Fedora Workstation 35 Please help me with this poor performance that I see on the wifi and bluetooth driver.

To clarify: did this machine work fine with earlier kernel series, like 5.16 or 5.15? And you filed this separately, as you assume the problem is different from https://bugzilla.kernel.org/show_bug.cgi?id=215748 ?
