Because Apples don't have eject buttons on the CD-drive, I have to punch in `cdcontrol eject' to remove a CD from the CD-ROM drive. For some reason, this causes a panic, right after the drive spits out the CD. >How-To-Repeat: $ cdcontrol eject The following trace will pop up: panic: Geom provider ACD::acd0 failed closing ->access() cpuid = 0 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2a panic() at panic+0x17a g_access() at g_access+0x2ff g_dev_close() at g_dev_close+0xbf devfs_close() at devfs_close+0x2dd vn_close() at vn_close+0xb6 vn_closefile() at vn_closefile+0x82 fdrop() at fdrop+0xdd closef() at closef+0x29 fdfree() at fdfree+0x10f exit1() at exit1+0x2d5 sys_exit() at sys_exit+0xe syscall() at syscall+0x1ba Xfast_syscall() at Xfast_syscall+0xab --- syscall (1, FreeBSD ELF64, sys_exit), rip = 0x80091e26c, rsp = 0x7fffffffeda8, rbp = 0x7fffffffee10 --- Trace with kgdb: #0 doadump () at pcpu.h:194 #1 0xffffffff8017f10c in db_fncall (dummy1=Variable "dummy1" is not available. ) at /usr/src/sys/ddb/db_command.c:486 #2 0xffffffff8017f62c in db_command_loop () at /usr/src/sys/ddb/db_command.c:401 #3 0xffffffff8018108f in db_trap (type=Variable "type" is not available. ) at /usr/src/sys/ddb/db_main.c:222 #4 0xffffffff802c8c95 in kdb_trap (type=3, code=0, tf=0xffffffffaf0b6520) at /usr/src/sys/kern/subr_kdb.c:502 #5 0xffffffff803f0e1a in trap (frame=0xffffffffaf0b6520) at /usr/src/sys/amd64/amd64/trap.c:472 #6 0xffffffff803d698e in calltrap () at /usr/src/sys/amd64/amd64/exception.S:169 #7 0xffffffff802c8e61 in kdb_enter (msg=0xffffffff80820fe0 "") at cpufunc.h:63 #8 0xffffffff802a1833 in panic (fmt=Variable "fmt" is not available. ) at /usr/src/sys/kern/kern_shutdown.c:547 #9 0xffffffff8025211f in g_access (cp=0xffffffff80581800, dcr=-1, dcw=0, dce=53103872) at /usr/src/sys/geom/geom_subr.c:749 #10 0xffffffff8024b4ff in g_dev_close (dev=0xffffff0003321200, flags=Variable "flags" is not available. ) at /usr/src/sys/geom/geom_dev.c:217 #11 0xffffffff8023af2d in devfs_close (ap=0xffffffffaf0b6840) at /usr/src/sys/fs/devfs/devfs_vnops.c:369 #12 0xffffffff803241b6 in vn_close (vp=0xffffff00033b0000, flags=1, file_cred=0xffffff00010bad00, td=0xffffff0003393350) at vnode_if.h:228 #13 0xffffffff803242b2 in vn_closefile (fp=0xffffff00033a1168, td=0xffffff0003393350) at /usr/src/sys/kern/vfs_vnops.c:868 #14 0xffffffff8027727d in fdrop (fp=0xffffff00033a1168, td=0xffffff0003393350) at file.h:297 #15 0xffffffff802784b9 in closef (fp=0xffffff00033a1168, td=0xffffff0003393350) at /usr/src/sys/kern/kern_descrip.c:1958 #16 0xffffffff802791af in fdfree (td=0xffffff0003393350) at /usr/src/sys/kern/kern_descrip.c:1668 #17 0xffffffff80281f95 in exit1 (td=0xffffff0003393350, rv=0) at /usr/src/sys/kern/kern_exit.c:271 #18 0xffffffff80282dfe in sys_exit (td=Variable "td" is not available. ) at /usr/src/sys/kern/kern_exit.c:98 #19 0xffffffff803f075a in syscall (frame=0xffffffffaf0b6c70) at /usr/src/sys/amd64/amd64/trap.c:825 #20 0xffffffff803d6b9b in Xfast_syscall () at /usr/src/sys/amd64/amd64/exception.S:290 #21 0x000000080091e26c in ??
