Apparently, minstrel_ht expects some tx_status field filled in by
brcmsmac/mac80211. Have not found the problem yet.

So the patch you sent fixes this? Just making sure it's not a different
thing.

Yes. I should probably have referred to this thread.

I have also seen the same crash in minstrel_tx_status, but it showed up in the middle of revising p54usb to use asynchronous firmware loading, and I thought I had some kind of subtle timing problem in the initialization. I certainly will test the patch and report back.
