https://bugs.freedesktop.org/show_bug.cgi?id=27786

           Summary: Freeze if boss-key (Shift-Esc) pressed while busy
                    doing network stuff and game engine not running
           Product: Mesa
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: luke-jr+freedesktop@utopios.org


If I press Shift-Esc while Armagetron Advanced is in a network-only state
(fetching server list, between rounds, etc), the game locks up until I manually
kill it (SIGINT works)

Looks like Armagetron Advanced or SDL is doing crazy stuff from a signal
handler...

My uneducated guess is that radeonFlush is triggering a SIGSEGV and libSDL is
trying to shutdown sanely as a result, which creates a loop since the
radeonFlush is already in the shutdown procedure.

Can you get another backtrace showing what signal it is, with debugging symbols
for at least r300_dri.so?

The classic r300 driver has been abandoned long ago.
It was replaced by the Gallium driver r300g.

If you have issues with r300g please file a new bug report with component
Drivers/Gallium/r300

Thanks.
