I have x86 box at home running current as of last night that began to behave this way: FreeBSD bobzilla 4.0-CURRENT FreeBSD 4.0-CURRENT #0: Sun Oct 17 21:45:50 EDT 1999 sto@bobzilla:/usr/src/sys/compile/BOBZILLA i386 ata-pci0: <Intel PIIX4 IDE controller> at device 7.1 on pci0 ata-pci0: Busmastering DMA supported ata0 at 0x01f0 irq 14 on ata-pci0 ata1 at 0x0170 irq 15 on ata-pci0 ad0: <WDC AC23200L/09.09M08> ATA-4 disk at ata0 as master ad1: <ST5540A/09.09.01> ATA-? disk at ata1 as slave acd0: <CD-532E/1.0A> CDROM drive at ata1 as master ata1-slave: ad_timeout: lost disk contact - resetting ata1: resetting devices .. done Once this ad_timeout happened, I was hosed. I had to power cycle my way out of a shutdown.. and upon reboot, the file system was completely toast. newfs was my only way out... fortunately, this was just my /usr/obj directory, so I am not too concerned about the lost data. Of course, this could just be a sign of the imminent demise of this drive. Hope this helps.
