This is merely the latest instance where I try to search BZ and wait and wait and wait and wait only to have the search silently fail. In the instant case, I deselected everything, put "DWARF2 unwinder stuck" in the comments box, and put 5y in the upper change history between box before clicking to proceed (search button). A blank page displays straight away, and stays that way for several minutes, with status bar initially displaying "Transferring data from bugzilla.opensuse.org...", then switching to "Done", without producing any change in the all white viewport. What can I do differently, without imposing unwanted restrictions, to nudge BZ into doing something useful searching for such a string?

The search intent was to find some kind of clue to making these oopses stop happening, but I'm having no luck figuring out where to start. An old SUSE forum thread indicated a solution had been found once upon a time, but without clues to access useful additional info: https://forums.suse.com/showthread.php?1913-Kernel-error-DWARF2-unwinder-stu... -- "The wise are known for their understanding, and pleasant words are persuasive."
