Hanging of 32-bit processors on Linux kernels branches 5.15-5.17

How to Solve Missing Kernel Headers Issue on Rocky Linux 8 / CentOS 8

Linux kernel versions 5.17 (March 21, 2022), 5.16.11 (February 23, 2022) and 5.15.35 (April 20, 2022) included a patch to fix the s0ix sleep entry issue on AMD processors, resulting in spontaneous freezes on 32- bit processors of x86 architecture. In particular, freezes are noted on Intel Pentium III, Intel Pentium M and VIA Eden (C7).

The problem was initially experienced by a Thinkpad T40 laptop owner who added a C3 mode exception for that platform, then an Intel developer found the problem on the Fujitsu Siemens Lifebook S6010 and fixed the bug with the original patch.

The bug fix has so far only been accepted into the upcoming 5.18-rc5 release and has not been backported to other branches.
