Bug#1019401: QSGRenderThread[569483]: segfault after suspend/resume
Hello, that will still not be enough for further investigation, but the given byte sequence in conjunction the package from snapshot.d.o including the dbgsym package points to this location: 0x...cfb in QThreadStorageData::get() const at thread/qthreadstorage.cpp:122 @piorunz: a first step might be to install the package systemd-coredump. That way a whole lot of information for a crash should appear in the journal. This link might contain more hints: https://wiki.debian.org/HowToGetABacktrace Kind regards, Bernhard (gdb) list qthreadstorage.cpp:114,125 114 void **QThreadStorageData::get() const ... 121 QVector = data->tls; 122 if (tls.size() <= id) 123 tls.resize(id + 1);

Or you can easily replicate it every time you suspend/resume your machine? Regards, Lisandro. Yes I think this is related to GPU driver (AMD Radeon card). Because its glitching sometimes and sometimes I have to kill X session. I will be happy to provide more logs and maybe move this bug to other relevant package, but how to catch and identify this bug in more detail? -- With kindest regards, Piotr. ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org/ ⠈⠳⣄
