They are recorded with mpt->verbose=2 . Those of you who might be interested in this problem can get two files from URLs below. http://www6.ocn.ne.jp/~mho/1750singledrive.txt.gz http://www6.ocn.ne.jp/~mho/1750tripledrive.txt.gz It seems to me that mpt0 sends requests endlessly in the case of 3 drives. As for revisions of the hardware, from BIOS information, LSI Logic 1030's revision is 1013D00 and IBM IC35L036's is S27F. Regards, Hori Masato
