Crash happens upon connect to WiFi. After my latest kernel and BIOS update from today I tried this about 10 times, and saw the same problem 100 % of the times.

See above.


>    Output from: lspci -mnn

Slightly modified to just show the wifi hardware -- let me know if more is needed.

$ lspci -mnn | grep -i network
6c:00.0 "Network controller [0280]" "Qualcomm [17cb]" "QCA6390 Wireless Network Adapter [AX500-DBS (2x2)] [1101]" -r01 "Rivet Networks [1a56]" "Device [a501]"


>   Output from: find /lib/firmware/ath11k/ -type f | xargs md5sum

Slightly modified the command to account for xz-compressed binary files:

$ find /lib/firmware/ath11k/QCA6390 -type f -print -exec sh -c 'cat {} | unxz | md5sum' \;
/lib/firmware/ath11k/QCA6390/hw2.0/amss.bin.xz

These are the same as shown by Kalle Valo here: https://bugzilla.kernel.org/show_bug.cgi?id=210923#c9


>    Output from: dmesg | grep ath11k

Slightly modified command to also show the "authenticate with ..." message, 0.2 seconds before the crash:

Ideally, this hardware would at some point soon work out of the box with Fedora 34. I however understand if that is utopia and in that case I would appreciate any help about what I could do to overcome this issue.

For the record, a bit of insight into the somewhat painful journey:

- I had previously tried to report problems via  https://bugzilla.redhat.com/show_bug.cgi?id=1950410 -- but said ticket got too complex.

- I reported a crash in ath11k_mac_op_unassign_vif_chanctx via  https://lore.kernel.org/ath11k/5b80d6b4-2956-0213-eeb8-c2229c7ec67c@googlemail.com/T/ -- but that was kernel 5.12.0 and did happen upon _searching_ networks, not upon connecting.
