>Description:
If my alcatel speedtouch is disconnected from the PC having had its firmware loaded, the system panics with a page fault. The firmware laoder program is from the net/pppoa port, and is called modem_run.exe. This used to work fine on 5.1-RELEASE.
I have the dump file available, if required.
gdb -k on the dump:

>How-To-Repeat:
Run modem_run to upload the modem firmware (e.g modem_run -f /usr/local/libdata/mgmt.o), wait for it to complete (it becomes a background process after uploading the firmware). Then unplug the modem.
