Hi Avery,

replying in smaller parts, easier to discuss that way.

Even if you are not using the latest and greatest ath10k I think you
should still post the firmware crashes. Then we can try to analyse
what's causing them.

What I'm wondering is that why you seem to have firmware crashes so
often. For example, I'm not seeing anything like that on our MIPS based
AP135 platform. Maybe there are more memory barrier issues like you
reported earlier?

What kind of platform are you using? Does it have any special
characteristics related to cache coherency, PCI access or similar?
