It takes a few hours between occurrences, possibly related to activity on the ntfs-3g filesystem. A kgdb trace is included below. I've already ensured that the fusefs module has been compiled against the correct kernel source. I've also checked the system with "freebsd-update IDS" and found no problems there. fusefs is the latest version from the ports tree: fusefs-kmod-0.3.9.p1.20080208_11 fusefs-libs-2.9.2 fusefs-ntfs-2012.1.15 #1 0xffffffff808ea3a1 in kern_reboot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:448 #2 0xffffffff808ea897 in panic (fmt=0x1 <Address 0x1 out of bounds>) at /usr/src/sys/kern/kern_shutdown.c:636 #3 0xffffffff80bd8240 in trap_fatal (frame=0xc, eva=Variable "eva" is not available. ) at /usr/src/sys/amd64/amd64/trap.c:857 #4 0xffffffff80bd857d in trap_pfault (frame=0xffffff822c0946e0, usermode=0) at /usr/src/sys/amd64/amd64/trap.c:773 #5 0xffffffff80bd8b9e in trap (frame=0xffffff822c0946e0) at /usr/src/sys/amd64/amd64/trap.c:456 #6 0xffffffff80bc315f in calltrap () at /usr/src/sys/amd64/amd64/exception.S:228 #7 0xffffffff8174ab17 in fiov_adjust () from /usr/local/modules/fuse.ko #8 0xffffffff8174b574 in fdisp_make_vp () from /usr/local/modules/fuse.ko #9 0xffffffff8174c04e in fuse_statfs () from /usr/local/modules/fuse.ko #10 0xfffffe000819ad20 in ??
