Description Ben Greear 2019-09-09 17:50:11 UTC 
We were doing some tests with an AX200 in station mode in an apu2 chassis.  We are not sure exactly what caused the crash at this time, but will update if we can reproduce.

Comment 1 Luca Coelho 2019-09-24 06:27:33 UTC 
Thanks for your report, Ben!

We have recently released a new version of the firmware (48) which also works on v5.2.  Can you update the firmware and keep an eye to see if it happens again?

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-cc-a0-48.ucode
Comment 2 Ben Greear 2019-10-02 20:59:45 UTC 
We have started using the v 48 firmware (that comes with Fedora-30).  It also has issues (see the UDP upload bugs), but maybe it doesn't have this exact problem.  Is the 'Status 0x90' the unique identifier for this bug?
Comment 3 Luca Coelho 2019-10-08 08:09:34 UTC 
The identifier for this bug is: 0x00000942 | ADVANCED_SYSASSERT

This is a know issue and our PHY team is already working on it
internally.  I don't have much more details at the moment, but I'll
update the bugzilla entry as soon as we know more.

Maybe the UDP upload problems you're seeing are the same as Sergey mentioned in the list?

Hi Ben,

How often do you reproduce this?
Comment 5 Ben Greear 2019-10-08 13:33:37 UTC 
We only noticed the 0x942 problem once.  The UDP upload issue is likely similar to what others have posted, though we can reliably hit it with slower speed traffic.
Comment 6 Luca Coelho 2019-11-20 19:40:40 UTC 
Today I found a bug in the driver that causes problems during high TX throughput (or rather, high number of frames that would cause mac80211 to use AMSDU).  Can you please try this patch and see if it helps with the issue you are experiencing?

Comment 7 robert.carter 2019-12-10 17:04:11 UTC 
Note, I'm seeing this 0x942 assert routinely when changing between managed and monitor mode. Failure is thrown ~20 out of 100 times when swapping modes.

Comment 8 Luca Coelho 2019-12-20 12:59:50 UTC 
Robert, did you have the patch I mentioned in comment #6 included? If not, can you check if you still get the 0x942 sysassert with that?
Comment 9 MHartman 2019-12-20 21:33:12 UTC 
I've confirmed with Bob (coworker) and examined the units, he was using your patch.  On 8 different units with AX200's that are running as either sniffers or stations, five of them had the 0x0942 ADVANCED_SYSASSERT, several with many.  Almost all show an association message in the dmesg just prior to the assert, eg:
