A DDB trace at the time of the panic is inside of checkalias(). >How-To-Repeat: Run mount -t mfs /dev/da0s1b /tmp on any -current system. >Fix: Luoqi Chen suggested changing NUMCDEV in src/sys/kern/kern_conf.c to 255. v1.39 of kern_conf.c has NUMCDEV at 256. Tested here and works fine. Apparently MFS uses CDEV 255 for it's own twisted purposes. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
