[Bug 27786] New: Freeze if boss-key (Shift-Esc) pressed while busy doing network stuff and game engine not running
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)

--- Comment #1 from Michel Dänzer michel@daenzer.net 2010-04-22 00:31:20 PDT --- Looks like Armagetron Advanced or SDL is doing crazy stuff from a signal handler...

--- Comment #2 from Luke-Jr luke-jr+freedesktop@utopios.org 2010-04-22 06:56:17 PDT --- 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.

--- Comment #3 from Michel Dänzer michel@daenzer.net 2010-04-22 07:04:02 PDT --- Can you get another backtrace showing what signal it is, with debugging symbols for at least r300_dri.so?

--- Comment #7 from Andreas Boll andreas.boll.dev@gmail.com --- 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.
