Gibbs > =========================================== > FreeBSD: Turning PCs into workstations > =========================================== Hello, I did the firmware upgrade for sd2, that is the newer disk which had firmware release L912. It did change nothing ! I submitted a followup to freebsd-gnats. I don't think I can do / need an update for sd0, the older disk. I think only firmware L912 had problems. But I faxed a question concerning the older disk to Quantum. No answer yet. Anyway, thanks for your hints ! -- Helmut F.

Apr 15 22:33:38 atlantis /kernel: sd0(ahc0:0:0): no longer in timeout END OF ERROR LOG The error seems to be on both unix disks sd0 and sd2 (sd1 is purely DOS/WIN95 and therefore not mounted). This sort of errors never occured while I was using FreeBSD-2.1.7-STABLE. Since switching to 2.2-STABLE (about two weeks ago) the system is unreliable and because of this error I cannot really use it. I have problems with the second Quantum ATLAS and DOS/WIN95, I cannot access it properly under DOS or Win95. I wrote to Adaptec, but got no usable answer. I think there is a bios problem, but it did not affect 2.1.7-STABLE so I think it has nothing to do with this bug. I am thinking of dumping this sorry excuse for an SCSI Adapter, have you any recommendations ?
