Unexpected busfree in Message-in phase
From: Jesper Juhl
Date: Sat Aug 11 2007 - 11:10:36 EST
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.
