Hmm, that's certainly "interesting"...

You say your baseline is a CC access point; there are so many moving
parts in this that it would be good to verify whether the crash is
caused by the softq patches specifically. Could you do an identical
build where you remove
package/kernel/mac80211/patches/337-ath9k-Switch-to-using-mac80211-intermediate-software.patch
(and any subsequent patches that touch the same code; i.e., the airtime
fairness patches), and see if that also causes crashes? :)
