Exact kernel version. Is it a distro kernel or have you compiled it yourself? Any extra patches? Linux version 5.15.45. Openwrt firmware with commit 67efb6a66146ac80986de928197b8116b2421779
Host device information. Router Xiaomi AX3600 based on ipq8072a 
BIOS version.
How many times have you seen the bug and how many times did you try to reproduce it? The firmware crash is present every time and the crash log is always the same.

This is the crash from the firmware. Firmware WLAN.HK.2.5.0.1-01208-QCAHKSWPL_SILICONZ-1 correctly works and handle wifi.

After this the firmware doesn't answer to any driver.
As an extra info the firmware crashed also with version 2.6.0.1 so the regression should be between 2.5.0.1 and 2.6.0.1.
Another router also based on ipq8074 hw 2.0 a QNAP 301w correctly works with 2.7.0.1 so there could be something specific with the xiaomi router that triggered the regression.

I attached the pre-cal and BDF file required to make the router correctly work.
Comment 1 Kalle Valo 2023-03-08 09:12:04 UTC 
I wonder if this is something board file related?
Comment 2 Robert Marko 2023-03-08 09:55:07 UTC 
It is, AX3600 has really old BDF that does not define regulatory regDbFlag nor regDbVersion so without external regdb.bin it will crash the FW as far as I know
Comment 3 Raj Kumar Bhagat 2023-05-09 07:56:32 UTC 
We have tried to reproduce the FW crash in other HK (HK-14) board with the shared board data and cal-data with the Firmware version 2.7.0.1-01744, we do not see the crash reported.

Christian Marangi (Ansuel) Would you be able to share the q6 crash dump for this crash. This would help us to debug further. Also please share the dmesg log with boot log enabled for ath11k.
Comment 4 Christian Marangi (Ansuel) 2023-05-10 12:11:23 UTC 
I'm happy to confirm that the regression is solved with firmware 2.9.

Are you still interested in bisecting this with 2.7?
Comment 5 Raj Kumar Bhagat 2023-05-10 13:41:25 UTC 
Glad to hear things are working with the FW 2.9.

Can you please help with the FW version point us to the firmware used?
