The 300 TX4 model is causing transient errors for several people, and we don't yet know why. In your case, port_status 0x00001000 means that "host bus is busy more than 256 clock cycles for every ATA I/O transfer" (quoting the docs). Basically it's a timeout. As long as it's transient, don't worry. You may want to try without hrt1 to see if hrt1 is causing the issue. /Mikael - 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/
