Greetings, I've a motherboard and disk drive that have been running on older versions of FreeBSD for quite a while, reliably. Recently, I moved to FreeBSD 6.0-RELEASE (and lately to 6.1-RELEASE, but it didn't help), and the system periodically shows: > ad4: FAILURE - device detached This is likely to happen under heavy I/O load (the machine serves a few dozen virtual websites, averaging 15 Mb/s sustained). Then the machine will eventually reboot. The motherboard is an MSI with an AMD 1.3 GHz CPU and 1.25GB of RAM, it has two IDE controllers, a VIA 8235, and a Promise (I can't access the machine right now to get the exact model number). The problem happens the same with either controller. I tried both UDMA100 and PIO4 modes, no difference. SMART reports a healthy drive, and as mentioned before, it didn't have problems with older versions of FreeBSD (5.4-RELEASE to be precise) and under similarly heavy load. The IDE cable was replaced, just in case, but again, no difference. Any ideas? -jav
