Hi Denis,
(resending as prior message to the iwd mailing-list was rejected as I was not a list
member)
thank you for forwarding this report to the right mailing list. I'm
adding the debug log below. The router triggering the issue is
ec:a8:1f:99:cf:f0. I noticed that the issue will not occur when
disabling Band Steering on the router and splitting the 2.4G and 5G
networks into two separate SSIDs.

After enabling (to collect the debug logs) and disabling again Band
Steering on the router, AX210 would no longer authenticate with the
router "denied authentication (status 33)" and finally cause kernel
crash, followed by a kernel hang that could only be resolved by
restarting the WiFi network (by logging into the router admin interface
from my phone and changing WLAN Mode setting "Mixed 802.11 a/n/ac/ax" to
"Mixed 802.11 n/ac" which triggers the router to shutdown and start
again the WiFi network) followed by another crash. These are probably
unrelated to this issue, but you may know if and where I could report
them so I'm including them here. This was with AX210 firmware version
68.01d30b0c.0 ty-a0-gf-a0-68.ucode and Linux 5.17.0-rc8.
