I'm happy to say that I've tested 2.2-GAMMA (around last Jan.) and found that the panic part of the problem had gone away. I still got mysterious messages about restarting the SCSI bus, etc... but the machine recovered. You might also experience spontaneous SCSI lock-outs at that time. You might want to give 2.2-GAMMA a try and see what behaviour you see. Also, a quick perusal of the mail archives (look for SCSI in the subject) will relate my findings. - Dave Rivers - > > Thanks > > Harry Reed > > ---------- > > From: Nathan Torkington > > To: freebsd-questions@freebsd.org > > Subject: 2.1.5->2.1.7 causes SCSI errors? > > Date: Wednesday, March 05, 1997 9:26 AM > > > > Our news machine worked just fine under 2.1.5, but barfed miserably > > when upgraded to 2.1.7.
