When I attempt to boot a 5.17.0 kernel built from the kernel.org sources, I see disk sector errors on my "sda" device, and the boot process hangs at the point where "systemd-udevd.service" starts. Rebooting on 5.16.0 works with no disk I/O errors of any kind. Assuming the 5.17.0 kernel or its associated initrd had bad sectors, I rebuilt both and saw no I/O errors during the build nor afterward when copying the new kernel into place under "/boot". Even tried a cross-compile build of a 5.17.0 alpha kernel on my x86_64 platform to save build time (34 hours for a native build on a PWS 433au vs. 2 hours on the x86_64 platform). That build produced identical results when I tried booting on it. If anyone else is seeing this and can get a head-start on bisecting, that would be very much appreciated. I won't be able to get to it for about a week and a half :-(. 5.16.0 works. 5.17.0 doesn't. Might get lucky and find that the offending changes happened in the first 5.17.0 release candidate. As always, sincere thanks in advance. --Bob
