After this has occurred, the user is prompted to manually enter the device name at the mountroot> prompt; for me, even this doesn't work, and the device is not listed in the output from the ? command.
This machine boots 7.2 without problems from the same device. Trying an 8-STABLE kernel from 5 September (identifies as 8.0-BETA4), here is the last bit of the kernel messages (typed): root mount waiting for: usbus2 usbus1 usbus0 uhub0: 2 ports with 2 removable, self powered uhub1: 2 ports with 2 removable, self powered root mount waiting for: usbus2 uhub2: 2 ports with 2 removable, self powered root mount waiting for: usbus2 ugen2.2: <TOSHIBA> at usbus2 umass0: <Toshiba TransMemory, class 0/0, rev 2.00/1.00, addr 2> on usbus2 umass0: SCSI over Bulk-Only; quirks = 0x0000 root mount waiting for: usbus2 umass0:0:0:-1: Attached to scbus0 Trying to mount root from ufs:/dev/da0s1a ROOT MOUNT ERROR: If you have invalid mount options, reboot, and da0 at umass-sim0 bus 0 target 0 lun 0 da0: <TOSHIBA TransMemory PMAP> Removable Direct Access SCSI-0 device da0: 40.000MB/s transfers da0: 3875MB (7936000 512 byte sectors: 255H 63S/T 493C) first try the following from the loader prompt: etc. This clearly shows the device being detected after mounting has failed. >How-To-Repeat: Install FreeBSD-8.0-BETA4 to a USB flash drive, and attempt to boot from it. >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "[email protected]"
