I have a laptop with an internal psm0 device and several USB ports. At home, I have one mouse plugged into one usb port. For travelling on the train, I have another mouse and due to the geometry of the situation, I plug it into another usb port. When I leave the house, I unplug the house mouse, and close the laptop ... note that it doesn't suspend. I've set the acpi lid_button to "NONE" ... meaning it doesn't even try. when I get on the train, I open the laptop and plug in the train mouse. As soon as this tries to attach, I get the included panic. This is recent behaviour ... but I'm not positive how recent. Within the last couple of weeks, I beleive. Here's the data from the crash dump: panic: make_dev() by driver ums on pre-existing device (maj=0, min=0, name=console) at line 492 in file /usr/src/sys/kern/kern_conf.c (kgdb) bt #0 doadump () at /usr/src/sys/kern/kern_shutdown.c:240 #1 0xc0516b31 in boot (howto=256) at /usr/src/sys/kern/kern_shutdown.c:374 #2 0xc0516dcc in poweroff_wait (junk=0xc067c6ea, howto=492) at /usr/src/sys/kern/kern_shutdown.c:552 #3 0xc04fc200 in make_dev (devsw=0xc1e81540, minornr=-543685724, uid=0, gid=0, perms=0, fmt=0xc0674ec4 "ums%d") at /usr/src/sys/kern/kern_conf.c:490 #4 0xc04d87ee in ums_attach (self=0xc6b4f880) at /usr/src/sys/dev/usb/ums.c:356 #5 0xc0529f05 in device_probe_and_attach (dev=0xc6b4f880) at device_if.h:39 #6 0xc04dc0ed in usbd_probe_and_attach (parent=0xc5dea800, dev=0xc6a98800, port=2, addr=2) at /usr/src/sys/dev/usb/usb_subr.c:900 #7 0xc04dc4cb in usbd_new_device (parent=0xc5dea800, bus=0xc5df5000, depth=0, speed=1, port=2, up=0xc5dea7c0) at /usr/src/sys/dev/usb/usb_subr.c:1114 #8 0xc04d4325 in uhub_explore (dev=0xc5dea900) at /usr/src/sys/dev/usb/uhub.c:480 #9 0xc04da91f in usb_discover (v=0xc5dde940) at /usr/src/sys/dev/usb/usb.c:717 #10 0xc04da416 in usb_event_thread (arg=0xc5dde940) at /usr/src/sys/dev/usb/usb.c:410 #11 0xc0506b48 in fork_exit (callout=0xc04da3cc <usb_event_thread>, arg=0xc5dde940, frame=0xdf980d48) at /usr/src/sys/kern/kern_fork.c:802 >How-To-Repeat: As above. >Fix: None. >Release-Note: >Audit-Trail: >Unformatted:
