Just tried what you mentioned and the kernel panics at the same spot above
on vm_kern.c. I'm glad I cloned my drives on a nightly basis so I booted

before rebooting.

Doesn't work for me because is this actually a kernel bug as there
were no panics with the same system/kernel config with the September 23,
