dmesg

Hi,

the firmware version 46.a41adfe7.0 on AC 9560 is failing with the error: FW error in SYNC CMD GEO_TX_POWER_LIMIT

This happens with kernel: 5.2.0 and 5.1.0

Firmware version 46.3cfab8da.0 seems to work fine.

hi!

So apparently the change dates from 2019-06-20, by Luca Coelho <luciano.coelho@intel.com>	

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=e58cbf78678fd872d0cf7ab858ba0030cd8695b0

I also tried with the firmware version: 46.0e6a7071.0 (from b44321804352ea595cddffbd8fad81a6c91c128d just before on the same day)

and it doesn't work either.

In summary, with both kernel 5.2.0 and 5.1.0,
46.3cfab8da.0  WORKS
46.0e6a7071.0  FAILS
46.a41adfe7.0  FAILS

Can you please run it with debug=0x80 or even better with debug=0xffffffff,
modprobe iwlwifi debug=0xffffffff

Hi!

I've tested the patch with linux 5.2.2
and firmware version 46.a41adfe7.0.

Appears to works fine!

just in case, I include the full debug log.
Comment 9 xavier B 2019-07-27 09:48:32 UTC 
For the record: 

updated to "Linux version 5.2.3-arch1-1-ARCH" with doesn't contain the change from attachment 283923 [details].
and firmware 46.a41adfe7.0 loads and works just fine.
