Hi, I'm using 4.1 stock kernel on imx cpu and 8897 wifi chip connected over pcie to cpu. I did stress test by disabling AP in loop when wifi card is connected to perform scanning and reconnect. After 25 attempts I'll get following and after that wifi is unusable: mwifiex_pcie 0000:01:00.0: Firmware wakeup failed mwifiex_pcie 0000:01:00.0: failed to get signal information mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state mwifiex_pcie 0000:01:00.0: failed to get signal information mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state mwifiex_pcie 0000:01:00.0: failed to get signal information mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state mwifiex_pcie 0000:01:00.0: failed to get signal information mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state mwifiex_pcie 0000:01:00.0: failed to get signal information mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state mwifiex_pcie 0000:01:00.0: failed to get signal information mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state ieee80211 phy0: deleting the crypto keys mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state ieee80211 phy0: deleting the crypto keys mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state ieee80211 phy0: deleting the crypto keys mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state ieee80211 phy0: deleting the crypto keys mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state ieee80211 phy0: deleting the crypto keys mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state ieee80211 phy0: deleting the crypto keys I did look to some new patches and found following patch [0] but it didn't help. Is there anything else I can try to fix this issue? Thanks a lot.
