Not much else to report today other than expanding my test base out to a
few more RHEL 7.5b hosts, and re-rolled the 1.6.22.1-1 SRPM again, and am
still seeing the same results universally. Every host fails to boot due to
a kernel panic when it tries to load the openafs DKMS kernel module.
My next move on Monday will be to try an actual kernel-specific kmod
instead of DKMS. If that works I'll be kind of sad since we've had great
luck with DKMS until now.
