page fault during boot on latest -HEAD
While booting, the machine panics (before mounting everything), pictures are:
I can't seem to be able to get a dump, so ... I can't provide it (nor "panic"
nor "call dumpsys" make a dump).

Ok, on both reports it looks like some recent sysctl work must have
broken sysctl. The kernel does a sysctl -a while booting in order
to help seed the random number generator.
Rumko, could you do a 'nm -n /kernel' (or wherever that kernel binary
resides) and track down the function containing the address 0xc045d724 ?
I'm guessing is related to the recent network/polling work.

No good, it looks like it can't trace back from the fault
Hmm. Can you boot into single-user mode and set the dump device
manually? Then exit out of the single-user shell to complete a
normal boot and hopefully get a kernel core dump out of it.
