Yeah, there is something strange happening between v5.9 and v5.10 we have not yet figured out. Most likely it has something to do with memory allocations and DMA transfers failing, but no clear understanding yet. But to keep things simple let's only discuss the MSI problem on this thread, and discuss the timeouts in the another thread: http://lists.infradead.org/pipermail/ath11k/2020-November/000641.html I'll include you and other reporters to that thread. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
