I am using twl4030 power buttom. Whenever I press the power key I get i2c controller timed out. I am seeing following logs and the keypad stops responding and I have to remove the board supply completely. i2c_omap i2c_omap.1: controller timed out i2c_omap i2c_omap.1: controller timed out twl4030: I2C error -110 reading PIH ISR i2c_omap i2c_omap.1: controller timed out twl4030: I2C error -110 reading PIH ISR i2c_omap i2c_omap.1: controller timed out twl4030: I2C error -110 reading PIH ISR i2c_omap i2c_omap.1: controller timed out When I enabled the logs I could see twl4030: i2c error -110 while reading TWL4030 PM_MASTER STS_HW_CONDITIONS register The behavior is seen mostly with power-button key. Is there any fix that has gone into the kernel for this(after 2.6.28-omap1)? -- Best Regards Pramod
