Created attachment 243521 [details] dmesg after resume from freeze mode After resume from freeze mode, wifi connection is lost, and a lot of mwifiex_pcie driver errors in dmesg. [ 229.126568] Restarting tasks ... done. [ 230.462523] [drm] RC6 on [ 231.582602] mwifiex_pcie 0000:02:00.0: Firmware wakeup failed [ 231.583938] mwifiex_pcie 0000:02:00.0: PREP_CMD: FW in reset state [ 231.583947] mwifiex_pcie 0000:02:00.0: scan failed: -1 Then I tried unloading and reloading mwifiex_pcie driver, and then system freezes and I need to reboot my system.
Note: We can't compare freeze to mem/ACPI-S3 on this system, because the MS Surface Pro3 does not support ACPI/S3.
The problem should be "mwifiex_pcie" driver is not stable. In 4.4 kernel, wifi is working for days, and then become unusable, even before suspend-to-idle. Now I have updated kernel to 4.10-rc2 and the problem becomes worse. It becomes unusable even after a couple of hours. dmesg is full of below error messages [17518.396212] mwifiex_pcie 0000:02:00.0: PREP_CMD: FW in reset state [17518.396215] mwifiex_pcie 0000:02:00.0: scan failed: -1 [17519.397678] mwifiex_pcie 0000:02:00.0: PREP_CMD: FW in reset state [17519.397686] mwifiex_pcie 0000:02:00.0: scan failed: -1 [17520.399299] mwifiex_pcie 0000:02:00.0: PREP_CMD: FW in reset state [17520.399304] mwifiex_pcie 0000:02:00.0: scan failed: -1 [17521.400932] mwifiex_pcie 0000:02:00.0: PREP_CMD: FW in reset state [17521.400943] mwifiex_pcie 0000:02:00.0: scan failed: -1 [17522.402873] mwifiex_pcie 0000:02:00.0: PREP_CMD: FW in reset state [17522.402877] mwifiex_pcie 0000:02:00.0: scan failed: -1 [17523.403870] mwifiex_pcie 0000:02:00.0: PREP_CMD: FW in reset state [17523.403874] mwifiex_pcie 0000:02:00.0: scan failed: -1

Could you try latest firmware? http://git.marvell.com/?p=mwifiex-firmware.git;a=commit;h=05e2f3a4acf4174ec507a3464a374ecb1b4ec011
I have not upgraded firmware before, and the following is what I did I downloaded pcie8897_uapsta.bin from the git repo you attached and copy it to /lib/firmware/mrvl/, but the problem still exists. dmesg shows [ 7.024492] mwifiex_pcie 0000:02:00.0: WLAN FW is active [ 7.142161] mwifiex_pcie 0000:02:00.0: info: MWIFIEX VERSION: mwifiex 1.0 (15.68.7.p77) [ 7.142165] mwifiex_pcie 0000:02:00.0: driver_version = mwifiex 1.0 (15.68.7.p77) [ 7.142549] mwifiex_pcie 0000:02:00.0 wlp2s0: renamed from mlan0 so I guess the firmware is successfully upgraded, right?
the wireless network usually breaks in one day. When it breaks, I get this in dmesg [ 1143.248229] skbuff: skb_over_panic: text:ffffffffc0654f24 len:3583 put:1353 head:ffff93cef6f77000 data:ffff93cef6f770e4 tail:0xee3 end:0xec0 dev:<NULL> [ 1143.248255] ------------[ cut here ]------------ [ 1143.248282] kernel BUG at net/core/skbuff.c:105!

The issue reported in Comment #8 and #9 has been fixed recently. Please try below change. https://patchwork.kernel.org/patch/9510541/
cool. I assume the patch can be applied on top of 4.10-rc8, right? Will try the patch and get back to you ASAP. Thanks for the quick response.

Hi Zhang Rui, If you don't see this issue can you kindly close the same? Thanks, Ganapathi
the problem still exists last time I checked this, probably half a year ago. I will test the latest upstream and update later.
