removing this kernel and reinstalling had no effect - same error.
Comment 2 Josh Boyer 2015-11-06 09:08:16 EST
Please attach the output of dmesg from a successfully booting kernel, as well as a digitial picture of as much of the backtrace as you can see on the failed boot.

Created attachment 1090694 [details] dmesg output from good boot

I do not have a camera or cell phone to take a digital picture of the screen, which I believe is what was requested.

Thanks, that was helpful. Looking at the versions you have, it seems like a patch added in 4.2.4 is causing your issue. Upstream is already aware of it, and the fix is queued for 4.2.6. Specifically it is: commit ababae44108b0e94b58eef6cb5bd830bd040a47f Author: Werner Pawlitschko <firstname.lastname@example.org> Date: Tue Oct 27 09:08:04 2015 +0900 x86/ioapic: Prevent NULL pointer dereference in setup_ioapic_dest() Commit 4857c91f0d19 changed the way how irq affinity is setup in setup_ioapic_dest() from using the core helper function to unconditionally calling the irq_set_affinity() callback of the underlying irq chip. That results in a NULL pointer dereference for the rare case where the underlying irq chip is lapic_chip which has no irq_set_affinity() callback. lapic_chip is occasionally used for the timer interrupt (irq 0). The fix is simple: Check the availability of the callback instead of calling it unconditionally.
