In the meantime, I rebuilt the kernel with vm and slub debugging
turned on, but actually nothing really informative came out
during dmesg.
Anyhow, it still oopsed, but obviously the IP was different.
Here's the new oops, with addr2line output below.
Unable to handle kernel paging request at virtual address a07ffffe5a7838a8
