I’ve had my BPi-M2U for over a year now. Installed the latest ubuntu mate at the beginning of this year.
Recently I have been having problems. Either the M2U wont let me SSH into the device, or it doesnt let me reboot it. I have to power cycle the device to get it to restart. The systemd-journald process runs at 100% cpu, and floods dmesg with:
sunxi-mmc sdc0: Has wait r1 rdy c23368 i1. I’ve read M2U stuck Post but I am using a newer kernel.
uname -a Linux bpi-iot-ros-ai 3.10.107-BPI-M2U-Kernel #1 SMP Thu Aug 24 08:01:24 CST 2017 armv7l armv7l armv7l GNU/Linux
Any help would be appreciated, thanks!
