I already said that: 1. This controller and disks succesfully works earlier with FreeBSD 4.6.2 without any problems; 2. I tried to replace a disk with another one (the same model), but it doesn't help. Unfortunately, I have no another free SCSI controller (but see #1); 3. I have another AMD64 machine with different hardware (including disks and SCSI controller) that periodically suffers from the same problem. Unfortunately, that machine is in production and heavily loaded, so I can't overload it even more with INVARIANTS, WITNESS, and DIAGNOSTIC - my clients will not forgive me for that. -- Oleg Derevenetz <oleg@vsi.ru> OOD3-RIPE Phone: +7 4732 539880 Fax: +7 4732 531415 http://www.vsi.ru CenterTelecom Voronezh ISP http://isp.vsi.ru
