Very strange indeed. Another possibility is that there is a hardware monitoring chip connected to one of the Radeon adapter's I2C buses, and that holding the I2C lines prevents reading from it, so whatever is responsible for controlling the temperature prefers to play it safe and shuts everything down. Somehow it seems more realistic than an actual overheating (3 seconds is a very short period of time for that), but we'd need the exact schematics of the hardware, and the details of the thermal control system, to validate this theory. Anyway, no need to worry anymore now that the bug is fixed :) -- Jean Delvare - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
