This is a case of the driver failing to load its firmware: May 16 11:49:01 ubuntu-phablet kernel: [ 29.811667] dw_mmc dw_mmc.1: Data0: Never released by cmd52 May 16 11:49:01 ubuntu-phablet kernel: [ 29.811806] dhdsdio_htclk: Failed access turning clock off: -35 May 16 11:49:01 ubuntu-phablet kernel: [ 29.811820] dhd_bus_start: dhdsdio_probe_download failed. firmware = /system/vendor/firmware/fw_bcmdhd.bin nvram = /system/etc/wifi/bcmdhd.cal May 16 11:49:01 ubuntu-phablet kernel: [ 29.811833] dhd_bus_devreset: dhd_bus_start fail with -1 May 16 11:49:01 ubuntu-phablet kernel: [ 29.811842] dhd_dev_reset: dhd_bus_devreset: -1 May 16 11:49:02 ubuntu-phablet kernel: [ 30.816669] dw_mmc dw_mmc.1: Data0: Never released by cmd52 May 16 11:49:02 ubuntu-phablet kernel: [ 30.816752] dhd_open : wl_android_wifi_on failed (-1) May 16 11:49:02 ubuntu-phablet kernel: [ 30.816760] wl_android_wifi_off in May 16 11:49:02 ubuntu-phablet kernel: [ 30.816771] dhd_prot_ioctl : bus is down. we have nothing to do May 16 11:49:03 ubuntu-phablet kernel: [ 31.821670] dw_mmc dw_mmc.1: Data0: Never released by cmd52 May 16 11:49:03 ubuntu-phablet kernel: [ 31.821811] wifi_set_power = 0
It needs more investigation in the kernel driver to figure out what's this cmd52 that is never released, and whether it is what's affecting firmware download, or if it's something else related. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1320249 Title: Manta has no network connection by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1320249/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
