Patch from Eric Norum <eric@skatter.usask.ca>:
I think I figured out why rtems_panic was locking up instead of
shutting down the executive and returning to the code that called
boot_card().
Later on there is code to print some messages on the standard error
stream, a recursive call back to rtems_verror (through rtems_error)
and finally a call to _exit().
I think that the _Thread_Disable_dispatch() is preventing the final
context switch back to the boot_card() code. Does this sound right
to you?
