It would be interesting if you could find out what you have at offset 0x830 of hyp-init.o (the stack trace is for EL1, and is not going to help much).
Given the alignment, i'm going to assume i'm looking at the right thing:
0000000000000820 <__kvm_hyp_reset>: 820: d51c2000 msr ttbr0_el2, x0 824: d5033fdf isb 828: d50c871f tlbi alle2 82c: d5033f9f dsb sy 830: 10000060 adr x0, 83c <__kvm_hyp_reset+0x1c> 834: b3403c01 bfxil x1, x0, #0, #16 838: d61f0020 br x1 83c: d53c1000 mrs x0, sctlr_el2
but it seems fairly implausible to be trapping on ADR x0, 1f...
... unless you've just switched TTBR0_EL2 to something slightly inappropriate, and conveniently flushed the TLBs. Also, having 0 as the exception class is fairly indicative you've fetched some crap, which reinforce my idea that the page tables are pointing to nowhere-land.
I'll try to review the patches next week, maybe I'll spot something by inspection.
Thanks,
