That's fine, although a bit frustrating. My initial guess is that we just don't have the DTS and drivers necessary, but maybe we can get that moving :) Here's the output for ofwdump -a root@f13:~ # ofwdump -a Node 0x38: Node 0xe4: interrupt-controller@48240000 Node 0x198: timer Node 0x200: rtc Node 0x264: aliases Node 0x290: chosen Node 0x2cc: cpus Node 0x2f8: cpu@0 Node 0x340: cpu@1 Node 0x39c: cpu@2 Node 0x3f8: cpu@3 Node 0x454: cpu@4 Node 0x4b0: cpu@5 Node 0x50c: cpu@6 Node 0x568: cpu@7 Node 0x5c8: soc Node 0x5d4: psci Node 0x610: clk24mhz Node 0x688: uart@3ff80000 Node 0x740: ufshc@1da4000 Node 0x7e0: ufs_phy@1da7000 Node 0x904: prlmbox@1da8000 Node 0x954: ehci@1da9000 Node 0x9d0: ahci@1daa000 Node 0xa4c: xhci@1dab000 Node 0xac8: video@1dc0000 Node 0xb54: tgate@1dc4000 Node 0xbf4: pci@2000000 Here's the boot loader output for fdt ls Type '?' for a list of commands, 'help' for more detailed help.

It came back up readily with kernel.old, which reports main-c255664-g4d64c7243d26 compiled Jan 9. In particular, how does one recognize which revision fixes this problem, assuming it's a bug and not operator error? Presumably, it'll take at least several days to reach git.
