My system is periodically hanging

This has been going on for a long time, but the last time I tried to diagnose it I didn't get far. This time, though, journalctl shows me a potentially helpful message:

Oct 16 17:15:23 homura kernel: BUG: unable to handle kernel NULL pointer dereference at 0000000000000001
Oct 16 17:15:23 homura kernel: IP: [<ffffffff811a600b>] kmem_cache_alloc+0x6b/0x170

My system has been hanging after a few hours of use, several times a day, for a long time now. This is the last thing journalctl shows the last few times it has happened.

Any ideas? Googling around hasn't been very useful.

I'm going through the tedious process of bisecting the kernel now...

Thank you! However, I'll note that this has been a problem since 3.13 and I couldn't solve it back then. I would help you bisect but the last time I tried, I couldn't get a custom kernel working with nvidia.
