Comment:
The `0x6b` byte in the fault address and a bunch of regs is the kernel's `POISON_FREE` value, a tell-tale sign of use-after-free. In the Void kernel, this poisoning is only performed when `slub_debug=P` is set on the kernel command line. It has measurable performance overhead, that's why nobody uses it in production. It was recently removed from the defaults (155b23d17543c31b5617bd6ea1943864370650ad), but stays enabled on existing installations.
Removing `slub_debug=P` from the kernel command line will most likely make the Oops disappear. Of course that's undefined behavior, but OTOH, that's how other distros are running this driver.
