That assessment (on my part) was premature. The attempt to boot from slice 4, running: FreeBSD g1-222.catwhisker.org. 9.0-CURRENT FreeBSD 9.0-CURRENT #3 r213357: Sat Oct 2 06:29:23 PDT 2010 root_at_g1-222.catwhisker.org.:/usr/obj/usr/src/sys/CANARY i386 immediately prior to the one I just did: * was using a kernel with the ATA_CAM enabled, as may be noted by the device name in: g1-222(9.0-C)[2] df -h / Filesystem Size Used Avail Capacity Mounted on /dev/ada0s4a 1.4G 327M 1.0G 25% / g1-222(9.0-C)[3] * hung at the previously-discussed point. It appears that running a kernel with option ATA_CAM may well reduce the probability of this apparently intermittent mode of failure. Peace, david -- David H.
