* summary: kernel oopses with wlanconfig ath0 destroy, almost always
reproducable when wep is used and station is
assosiated. => Kernel oopses in ath_draintxq,
and other cases where
Comment:
Sorry, above I meant ath_buf* not ath_node.
When releasing an ath_buf* the second time, at least one duplicate
invocation of dev_kfree_skb_* will happen on the same memory address. The
kernel memory allocator is asked to reclaim the same address. Depending
on the allocator this can cause various pathology, but do not be fooled
into thinking it's ok. I'm working on a proper fix for the problem, and a
quick and dirty fix.
