Thanks, good to know. On what platform is this, can you share more details? Is it the new Dell XPS 13 9310 or something else? > I do see a number of taints in dmesg while connecting to an access > point but the taint doesn't seem to affect functionality, for example: > https://pastebin.com/raw/gbzuvs3q This commit should fix that: https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=ath11k-qca6390-bringup&id=fa4eea695afb286ae38beb30dabf251335cb4a62 I recommend using ath11k-qca6390-bringup branch, it has quite a few fixes: https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/log/?h=ath11k-qca6390-bringup > Finally, rebooting the computer does require a hard power down.

My uptime is now at 2 days with Fedora Rawhide kernel 5.10.0-0.rc6 with commit 59c6d022df8efb450f82d33dd6a6812935bd022f and a revert of 7fef431be9c9 patched in. I'm not experiencing any of the stalls or crashes that others have been mentioning and I have been able to suspend/resume consistently. No issues with power being plugged and unplugged either. Happy to help provide details if anybody needs any. > You mean that the reboot stalls and you need to turn off the laptop using power button? Actually, with the previously mentioned commit combination, I was able to shutdown and reboot successfully as well. -- ath11k mailing list ath11k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath11k ^ permalink raw reply [flat|nested] 4+ messages in thread

In fact, I found a reproducible way to lock up the system: 1. Turn off WiFi 2. Reboot system 3. Login 4. Turn on WiFi If you perform those steps, the system will lock on ath11k-qca6390-bringup, dmesg: https://i.imgur.com/0XExack.jpg On 59c6d02 + revert of 7fef431be9c9, the firmware will crash but the system will not lock up. dmesg: https://pastebin.com/raw/hH0HyWVx If you keep WiFi on, i.e. the system is automatically connected to WiFi on boot, then on the ath11k-qca6390-bringup tag, it randomly freezes. On 59c6d02, it seems to be fairly stable so long as I do not turn off/turn on WiFi. I can bisect based on the reproducible steps in the next couple days if nobody else comes up with something first.
