OK, it was able to relink kernels and reboot in a loop (I modified my /usr/libexec/reorder_kernel script to start with sleep 60 and end with reboot) for about 9 hours, then it had a hang after "checking quotas: done." Cycling power and booting again on the same kernel got past that point though, after fscking, so I'm going to mark that down as a fluke. Maybe the microsd card had a problem, maybe there was a power glitch. In any case, it's a LOT better than it was before. I was not able to do this relinking loop for more than ~30 minutes without having a hang before. > > > > Index: arch/arm/arm/locore.S > > > > =================================================================== > > > > RCS file: /cvs/src/sys/arch/arm/arm/locore.S,v > > > > retrieving revision 1.13 > > > > diff -u -p -r1.13 locore.S > > > > --- arch/arm/arm/locore.S 6 Jan 2017 00:06:02 -0000 1.13 > > > > +++ arch/arm/arm/locore.S 27 Feb 2018 21:27:10 -0000 > > > > @@ -101,6 +101,7 @@ ASENTRY_NP(start) > > > > .align 2 > > > > > > > > .bss > > > > + .align 3 > > > > svcstk: > > > > .space INIT_ARM_STACK_SIZE > > > > > > > > @@ -179,6 +180,7 @@ ENTRY(longjmp) > > > > mov pc, lr > > > > > > > > .data > > > > + .align 2 > > > > .global _C_LABEL(esym) > > > > _C_LABEL(esym): .word _C_LABEL(end) > > > > > > > > > > > > -- Brandon Bergren Technical Generalist
