Seeing a large jump from linux-raspberrypi-4.14.98-1-armv7h.pkg.tar.xz to linux-raspberrypi-4.19.23-1-armv7h.pkg.tar.xz and after applying this, my pi failed to boot, had to chroot via my desktop and restore the 4.14 kernel to boot up again.
Not sure how to get "pretty" boot failure output, but I took a video and it starts right after $this->bbcode_second_pass_code('', 'Starting Rebuild Journal Catalog'), which I'm assuming is due to all of the unplugging/re-plugging that I had done while trying to figure this out.
The only clear line that I get is
$this->bbcode_second_pass_code('', 'kernel BUG at mm/slub.c:3901!
Internal error: Oops - BUG: 0 [#1] PREEMPT SMP ARM')
Once the output stops scrolling I see:
$this->bbcode_second_pass_code('', '
Kernel panic - not syncing: Fatal exception in interrupt
CPU1: stopping
CPU: 1 PID: 0 Comm: swapper/1 Tainted: G D C 4.19.23-1-ARCH #1
Hardware name: BCM2835
... stack
SMP: failed to stop secondary CPUs
')
with some address and stack information after that (unwind_backtrace -> show_stack -> dump_stack -> handle_IPI -> __irq_svc -> arch_cpu_idle -> do_idle -> cpu_starup_entry)
Anyone have any advice? Could be an issue on my side, I assume that there are other RPi2 users here running the latest kernel with no problem.
