everything runs fine until I load ehci and if_rum, kernel panics a second or so afterwards while I am in the middle of fiddling with the new wlan stuff. the panic message always says something about usbtask or ehci. the machine for some reason stops at the dumping phase and doesn't go any farther, so I have no core dump How-To-Repeat: load if_rum and wait a few seconds

State Changed From-To: open->feedback any chance we can get a backtrace?
Gar. I had to rebuild the kernel with all the debugging stuffs. Then loading the usb modules just locked up the laptop, no dumps, so now the usb modules are compiled into the kernel. #0 doadump () at pcpu.h:246 #1 0xc05927ae in boot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:420 #2 0xc0592a82 in panic (fmt=Variable "fmt" is not available. ) at /usr/src/sys/kern/kern_shutdown.c:576 #3 0xc048a287 in db_panic (addr=Could not find the frame base for "db_panic". ) at /usr/src/sys/ddb/db_command.c:478 #4 0xc048a8b1 in db_command (last_cmdp=0xc08a8e9c, cmd_table=0x0, dopager=1) at /usr/src/sys/ddb/db_command.c:445 #5 0xc048aa0a in db_command_loop () at /usr/src/sys/ddb/db_command.c:498 #6 0xc048c86d in db_trap (type=12, code=0) at /usr/src/sys/ddb/db_main.c:229 #7 0xc05bf686 in kdb_trap (type=12, code=0, tf=0xc3bc0bbc) at /usr/src/sys/kern/subr_kdb.c:534 #8 0xc07ddd3f in trap_fatal (frame=0xc3bc0bbc, eva=56) at /usr/src/sys/i386/i386/trap.c:920 #9 0xc07ddf60 in trap_pfault (frame=0xc3bc0bbc, usermode=0, eva=56) at /usr/src/sys/i386/i386/trap.c:842 #10 0xc07de923 in trap (frame=0xc3bc0bbc) at /usr/src/sys/i386/i386/trap.c:522 #11 0xc07c334b in calltrap () at /usr/src/sys/i386/i386/exception.s:165 #12 0xc05110f4 in ehci_idone (ex=0xc3fca600) at /usr/src/sys/dev/usb/ehci.c:914 #13 0xc0511a9a in ehci_softintr (v=0xc4012000) at /usr/src/sys/dev/usb/ehci.c:802 #14 0xc052a1e2 in usb_schedsoftintr (bus=0xc4012000) at /usr/src/sys/dev/usb/usb.c:848 #15 0xc051362e in ehci_intr1 (sc=0xc4012000) at /usr/src/sys/dev/usb/ehci.c:631 #16 0xc0514105 in ehci_intr (v=0xc4012000) at /usr/src/sys/dev/usb/ehci.c:590 #17 0xc0573ee5 in intr_event_execute_handlers (p=0xc3d617d4, ie=0xc3da0b00) at /usr/src/sys/kern/kern_intr.c:1134 #18 0xc0574b5f in ithread_loop (arg=0xc4056be0) at /usr/src/sys/kern/kern_intr.c:1147 #19 0xc0571ca8 in fork_exit (callout=0xc0574ac0 <ithread_loop>, arg=0xc4056be0, frame=0xc3bc0d38) at /usr/src/sys/kern/kern_fork.c:815 #20 0xc07c33c0 in fork_trampoline () at /usr/src/sys/i386/i386/exception.s:270 -- The Mafia way is that we pursue larger goals under the guise of personal relationships.
