Subject: Re: [PATCH] ath10k: Add interrupt summary based CE processing
My previous email wasn't sent out.
At first I gave these 3 patches.
ath10k: Add interrupt summary based CE processing
https://patchwork.kernel.org/patch/11628299/
ath10k: Keep track of which interrupts fired, don't poll them
https://patchwork.kernel.org/patch/11654631/
ath10k: Get rid of "per_ce_irq" hw param
https://patchwork.kernel.org/patch/11654633/
and saw the crash happen and then reverted the top 2 and used the very
first one, but it is still happening.
