These time outs are very similar (in appearance at least) to the same type of problems I reported in 2.1.6 with my SCSI tape and SCSI CD-ROM on an aha2940 - except they would lock up the entire SCSI bus in my case... However, in 2.1.7 my problem was improved somewhat; in that only the one process would lock up. In 2.1.7.1 my problem was worsened in that the entire machine locks up. In a GAMMA version of 2.2 the problem was slightly improved, in that I would see the messages; (and, presumably my tape was not correctly written), but the machine wouldn't lock up; nor would the process.. but, I was running that in single user mode without the need for a swap, so no other SCSI activity was occuring. Anyway, it's my experience that things are improving in this area, but not quite there yet... As a counter point; at work a friend has several SCSI devices on two aha2940s; using a 2.2-GAMMA release; not a single problem... - Dave Rivers - > > Any other suggestions ??
