I'm trying to bring up LA.BR.1.3.7.c25 added to xperia's so called unified kernel (z1 8974 to z5 8994) LA.BR.1.3.3, so far i've got the same issue, i also found that: 505510e59c86ff283a2eb743f679debc6698d1ed 'clocksource: arch_timer: make virtual counter access configurable' caused

<6>[ 10.479964] init[1]: undefined instruction: pc=0000007fa4d704c8' at least trying aosp 7.1 that f2fs patch doesn't apply to the revision currently though ;(

According to your describe，kernel message early print

"undefined instruction: pc=%p\n"

may come from kernel arch timer startup phase.

As for f2fs, you‘d better watching the f2fs upstream history and modify your kernel side. This repository is not a general backport. It has changed pick a lot from kernel upstream with my changes...
