Hi, latest 12.2-stable r366421, when nothing is connected, i2c -s just hangs and reboot is required. if anything is connected, it just goes into a loop: # i2c -s Hardware may not support START/STOP scanning; trinterrupt storm detected = on "gic0,s6:"; throttling interrupt source ying less-reliable read method. interrupt storm detected on "gic0,s6:"; throttling interrupt source interrupt storm detected on "gic0,s6:"; throttling interrupt source =E2=80=A6 im willing to help debug this, but need help. cheers, danny
