Config: Asus SC200 (ncr810) in Asus P2L97 M/B with PII-300 and 128MB mem. With "hard" disk access (Make world; or Make release), more than likely, the ncr driver will give an error message of ncr:::queue empty, at which point the system will lock up (pager errors, etc). This is almost 100% reproducible. The SCSI drives are "old" Conner Cp3470. I'm not sure if there were problems with tagged queueing in this model; but they worked OK in a DG/UX system. The ncr driver previously reports that "tagged openings is now 31". Reverting to a kernel dated "8-Aug-1998" alleviates the problem. Any thoughts ?? Harry.
