Title:
ath11k_pci firmware crashes under regular usage on Dell XPS 13 9310
(no suspend and resume)
Status in linux-oem-5.10 package in Ubuntu:
Confirmed
Bug description:
While I was normally working on my Dell XPS 13 9310 Laptop, noticed
that WiFi suddenly got disconnected. Looking at dmesg, noticed that
the firmware crashed.
(I am also attaching the entire dmesg output as a file to this bug. )
$ dmesg | grep ath11_k

I had to reboot the machine at least 2 times before WiFi started
working. In the past, I had noticed WiFi would not work after boot a
couple of times, but this is the first time I am seeing it breaking
under normal, continuous usage. This is a major reliability issue if
WiFi connection keeps breaking in the middle of work like this.
Also, this is somewhat similar to the following bugs, but not exactly
the same:
https://bugs.launchpad.net/ubuntu/+source/linux-oem-5.10/+bug/1944018
(here there is no message 'firmware crashed' but rather some failures
from ath11k_pci. Moreover it occurred during suspend and resume.
Whereas in my case, the last suspend + resume was at least 3 and half
hours before the firmware crash)
https://bugs.launchpad.net/ubuntu/+source/linux-signed-
oem-5.10/+bug/1942060 (here there is 'firmware crashed' message, but
all the error messages after that seem to be different. Moreover it
seems to have occurred 56 seconds after system booted, when WiFi
network was connected. Whereas I had a uptime of 9 hours and about 6
hours after the last WiFi connection).
