Dear Mark, Sorry for the incorrect mail format, so i resent it again. Here has a problem when we put the 7042 on the kirkwood platform(6281). When system starting to build software raid 5, sometimes it would meet the unable to stop eDMA problem in all channels. And then whole system is being hang ... All the phy mode value are also not correctly if we read it out at that time. Could you please kindly have a look at the error messages and give some advice for me to find out the root cause ? Thanks. Thanks again. ------------- ata4: Unable to stop eDMA ata4.00: exception Emask 0x52 SAct 0x1f SErr 0xffffffff action 0xe frozen ata4: SError: { RecovData RecovComm UnrecovData Persist Proto HostInt
