Hi all Hopefully this has been asked before, because then there might be a solution already :-)
Long story short: ================ - Connect a putty terminal trough wifi to an NXP imx6 with Qualcomm Atheros QCA9377, using ath10k_sdio - type "ping -f <gateway>", e.g ping -f 192.168.10.1. The terminal window locks up and need to be killed from the client. This is observed at the serial debug console: [86574.617400] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12 [86574.624725] ath10k_sdio mmc1:0001:1: failed to submit frame: -12 [86574.630852] ath10k_sdio mmc1:0001:1: failed to push frame: -12 [86574.774034] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12 [86574.781373] ath10k_sdio mmc1:0001:1: failed to submit frame: -12 [86574.787409] ath10k_sdio mmc1:0001:1: failed to push frame: -12 The imx6 wifi doesn't die completely, just the dropbear/ssh connection. A new putty terminal can be opened without problem. Has anyone seen this? Is there a solution?
