Hiho! :-)
Following an unclean shutdown (panic, related to a bad network card in
another machine), my gjournaled external usb drive reliably crashes my
system when I connect it. I got a core dump available for poking around
further. Textdump info is attached. I'm not sure if the disk is dying
or the journal somehow got into a really bad state. textdump is
available on request! :-)
