Hi, I just noticed this in dmesg : [ 3216.262987] (scsi0:A:4:0): Unexpected busfree in Message-in phase [ 3216.263058] SEQADDR == 0x16c [ 3216.263724] target0:0:4: FAST-10 SCSI 10.0 MB/s ST (100 ns, offset 16) That's all there is in addition to the normal bootup messages, just those 3 lines. The machine is doing fine at the moment, no ill effects so far, but an explanation of what exactely could be causing that and whether or not it is a (fixable) problem would be very nice :-) Some details : $ scripts/ver_linux If some fields are empty or look unusual you may have an old version. Compare to the current minimal requirements in Documentation/Changes.
