I switched to the recommended proprietary nvidia driver, and since then there have been no hangs.
So either some update may have fixed it, or it's in the Nouveau driver, or I'm just lucky.
I should try switching back to Nouveau to see if it comes back, and if it does, I could then try the mainline kernel.
