[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.

Vendor: ATA Model: C400-MTFDDAT064M Rev: 07MH Type: Direct-Access ANSI SCSI revision: 05 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 ? >>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 -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
