I think the same sort of panic has occured when I tried playing CD's on this drive as well. It looks like some sort of race because these panics aren't persistent but seem to happen when I start up cdcontrol or ogle too quickly. Just a guess. I have another backtrace for CD playback with an older kernel. #0 doadump () at /usr/src/sys/kern/kern_shutdown.c:240 #1 0xc0494db4 in boot (howto=0x100) at /usr/src/sys/kern/kern_shutdown.c:372 #2 0xc0495158 in panic () at /usr/src/sys/kern/kern_shutdown.c:550 #3 0xc05b6a9c in trap_fatal (frame=0xd87e8c44, eva=0x0) at /usr/src/sys/i386/i386/trap.c:821 #4 0xc05b6762 in trap_pfault (frame=0xd87e8c44, usermode=0x0, eva=0x1c) at /usr/src/sys/i386/i386/trap.c:735 #5 0xc05b62fd in trap (frame= {tf_fs = 0xc0c30018, tf_es = 0xc44c0010, tf_ds = 0xc44c0010, tf_edi = 0x0, tf_esi = 0xc44c0380, tf_ebp = 0xd87e8c98, tf_isp = 0xd87e8c70, tf_ebx = 0xc44a8960, tf_edx = 0x0, tf_ecx = 0xc061cd84, tf_eax = 0x1, tf_trapno = 0xc, tf_err = 0x0, tf_eip = 0xc04b15d3, tf_cs = 0x8, tf_eflags = 0x10207, tf_esp = 0xc045c77e, tf_ss = 0xc44cd480}) at /usr/src/sys/i386/i386/trap.c:420 #6 0xc05a8168 in calltrap () at {standard input}:94 #7 0xc0461038 in g_destroy_provider (pp=0xc44a8960) at /usr/src/sys/geom/geom_subr.c:426 #8 0xc045dff5 in g_orphan_register (pp=0xc44c0380) at /usr/src/sys/geom/geom_event.c:147 #9 0xc045e11c in one_event () at /usr/src/sys/geom/geom_event.c:173 #10 0xc045e345 in g_run_events () at /usr/src/sys/geom/geom_event.c:206 #11 0xc045f365 in g_event_procbody () at /usr/src/sys/geom/geom_kern.c:134 #12 0xc047e130 in fork_exit (callout=0xc045f340 <g_event_procbody>, arg=0x0, frame=0x0) at /usr/src/sys/kern/kern_fork.c:793 >How-To-Repeat: Plop a CD/DVD in my drive and start cdcontrol/ogle. >Fix: __________________________________ Do you Yahoo!?
