We had the identical problem on a Mylex 486/33 EISA system from Tangent
Computer.  We tried AT&T and Dell Unix SysVr4 and neither we nor their
technical support groups could (or would) find anything (not my box attitude).
Microport and Tangent Computer got together and found a buggy Western Digital
driver.  Microport has a replacement driver downloadable from their tech
support bulletin board.  Perhaps you can get a repaired driver from ISC, too.
