When I do "modprobe ath9k" on ASUS-WL-500gP (MIPS) with _ath5k_ card (so, no
ath9k hardware), it says "Reserved instruction in kernel code" - is it
expected?

No.

The kernel is 2.6.31.1.

This says not tainted.

(...)

[  165.440000] Disabling lock debugging due to kernel taint

But this says kernel taint.

Yep, I saw this as well.

About every oops or panic on this hardware says "Disabling lock debugging due to kernel taint", no idea why.
