PROBLEM: Marvell 88W8797 wifi (module mwifiex) does not work on Surface Pro
[1.] One line summary of the problem
The system hangs when using the wifi connection.
[2.] Full description of the problem/report
I'm running the latest kernel (v4.1.0) on a Microsoft Surface Pro. Up to the 3.16 series, the wifi was basically working although the connection would drop from time to time. Now, it's not usable anymore: I can connect to a wifi network, the connection is working for a few seconds but the whole system hangs afterwards.
I tried using the marvell firmware fromgit://git.marvell.com/mwifiex-firmware.git, that didn't change anything.
The only error messages I noticed in /var/log/syslog are :
usb 1-3: failed to get signal information
followed by a lot of:
usb 1-3: PREP_CMD: FW is in bad state

Subject: PROBLEM: Marvell 88W8797 wifi (module mwifiex) does not work on Surface Pro[1.] One line summary of the problem
The system hangs when using the wifi connection.
[2.] Full description of the problem/report
I'm running the latest kernel (v4.1.0) on a Microsoft Surface Pro. Up to the 3.16 series, the wifi was basically working although the connection would drop from time to time. Now, it's not usable anymore: I can connect to a wifi network, the connection is working for a few seconds but the whole system hangs afterwards.
Quoted 6 lines
I tried using the marvell firmware from
git://git.marvell.com/mwifiex-firmware.git, that didn't change anything.The only error messages I noticed in
/var/log/syslogare :usb 1-3: failed to get signal information
Thanks for reporting this issue. Could you please let me know FW version? This is part of dmesg logs after driver is loaded. Also if possible could you please enable dynamic debug and share verbose logs?
Quoted 3 lines
followed by a lot of:
usb 1-3:
PREP_CMD: FW is in bad state
This suggests that FW has crashed/command timeout.

Subject: PROBLEM: Marvell 88W8797 wifi (module mwifiex) does not work on Surface Pro
[1.] One line summary of the problem
The system hangs when using the wifi connection.
[2.] Full description of the problem/report
I'm running the latest kernel (v4.1.0) on a Microsoft Surface Pro. Up to the 3.16 series, the wifi was basically working although the connection would drop from time to time. Now, it's not usable anymore: I can connect to a wifi network, the connection is working for a few seconds but the whole system hangs afterwards.
I tried using the marvell firmware from
git://git.marvell.com/mwifiex-firmware.git<http://git.marvell.com/mwifiex-firmware.git>, that didn't change anything.
The only error messages I noticed in /var/log/syslog are :
usb 1-3: failed to get signal information
Thanks for reporting this issue. Could you please let me know FW version? This is part of dmesg logs after driver is loaded. Also if possible could you please enable dynamic debug and share verbose logs?
followed by a lot of:
usb 1-3: PREP_CMD: FW is in bad state
This suggests that FW has crashed/command timeout.

Thanks for your fast answer.
As for the driver version, I have :
driver version = mwifiex 1.0 (14.68.29.p38)
Is that what you need ?
Quoted 1 line
Quoted 1 line
Also, how do I enable dynamic debug ?
You need to recompile kernel with CONFIG_DYNAMIC_DEBUG option. After booting into kernel, enable dynamic debug logging on mwifiex modules:
#echo "module mwifiex +p" > /sys/kernel/debug/dynamic_debug/control #echo "module mwifiex_usb +p" > /sys/kernel/debug/dynamic_debug/control
Thanks,
Avinash
