I had been seeing kernel lockups when doing soft resets, and JTAG debug pointed me an infinite loop in the omap_i2c_read_reg function. I added a timeout, as can be seen in my patch here: http://marc.info/?l=linux-omap&m=121995188317408&w=2 You are seeing this message instead of a kernel hang :^) -Jason Marini -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
