Hi,
My Arch system seems to be crashing with the same issue, here twice in a row.
Although it's a specific distro (Arch), I think it's a relevant bug, it seems
to affect the Kernel, Arch doesn't mess around with the Kernel, and it's a
serious bug (NULL ptr deref), and I have two independent traces. See below.
