Until I realized what was in the Modular Bay: the CD/CVD reader/burner. So I tried a variation on the theme: I left all the devices enabled, but I physically removed the device from the bay before booting -- and was unable to get it to fail. And -- just now -- I disabled the channel (via atacontrol(8)), inserted the drive, and enabled the channel: g1-222# atacontrol list ATA channel 0: Master: no device present Slave: no device present ATA channel 1: Master: no device present Slave: no device present ATA channel 2: Master: ad4 SATA revision 2.x Slave: no device present ATA channel 3: Master: no device present Slave: no device present ATA channel 4: Master: no device present Slave: no device present ATA channel 5: Master: no device present Slave: no device present g1-222# atacontrol detach ata3 g1-222# atacontrol list ATA channel 0: Master: no device present Slave: no device present ATA channel 1: Master: no device present Slave: no device present ATA channel 2: Master: ad4 SATA revision 2.x Slave: no device present ATA channel 3: Master: no device present Slave: no device present ATA channel 4: Master: no device present Slave: no device present ATA channel 5: Master: no device present Slave: no device present g1-222# atacontrol attach ata3 Master: acd0 SATA revision 1.x Slave: no device present g1-222# atacontrol list ATA channel 0: Master: no device present Slave: no device present ATA channel 1: Master: no device present Slave: no device present ATA channel 2: Master: ad4 SATA revision 2.x Slave: no device present ATA channel 3: Master: acd0 SATA revision 1.x Slave: no device present ATA channel 4: Master: no device present Slave: no device present ATA channel 5: Master: no device present Slave: no device present g1-222#=20 This is running: FreeBSD g1-222.catwhisker.org. 9.0-CURRENT FreeBSD 9.0-CURRENT #1 r213322: = Fri Oct 1 10:18:30 PDT 2010 root@g1-222.catwhisker.org.:/usr/obj/usr/s= rc/sys/CANARY i386 Any ideas on what mught be causing CURRENT to hang -- sometimes -- given that it appears to involve the Modular Bay (or the specific device that is in the bay during the hang)?
