Hi,
v5.4.y commit 3cf391e4174a ("wifi: ath10k: Don't touch the CE interrupt registers after power up"), which is commit 170c75d43a77 upstream, unleashed multiple DB845c(sdm845) regressions ranging from random RCU stalls to UFS crashes as also reported here https://lore.kernel.org/lkml/20230630151842.1.If764ede23c4e09a43a842771c2ddf...
Taking a cue from the commit message of 170c75d43a77, I tried backporting upstream commit d66d24ac300c ("ath10k: Keep track of which interrupts fired, don't poll them") and other relevant fixes and that seem to have done the trick.
We no longer see any of the above reported regressions with the following patchset. This upstream patchset is just an educated guess and there may be one or more fixes in this series which are not needed at all but I have not tested them individually and marked all of them as Stable-dep-of: 170c75d43a77 ("ath10k: Don't touch the CE interrupt registers after power up") instead.
All now queued up, thanks.
