A small addition: if I login from the console (ttyv0 this time) and
start pbulk program inside a GNU screen session,
  $ screen bulkbuild

detach it,
  (ctrl-A d)

reattach to it,
  $ screen -r

detach it again,
  (ctrl-A d)
then logout from the console and the kernel panics too.  If I log into
this machine via ssh and do the same thing, the kernel won't panic,
 so this may be specific to ttyvN.
