Thank you for the report! I am afraid that ABRT cannot do much in this matter. It might happen that the kdeinit4 process messes up its own memory in the way that the core file cannot be successfully loaded by gdb. Can you please turn of abrt, generate several core files using pure kernel core file handler and try to generate backtrace from each of the core files? # systemctl stop abrt-ccpp # mkdir /var/tmp/cores/ # echo "/var/tmp/cores/core.%P" > /proc/sys/kernel/core_pattern ... reproduce the crash # cd /var/tmp/cores/ # for c in $(ls core*); do gdb -c $c; done I do not think NVIDIA kernel drivers can break user space process memory. You can try to run kdeinit4 in valgrind to detect memory errors, but that might be extremely time consuming operation. I am not able to reproduce this problem and it looks like it is third party software issue hence I am closing it. Please feel free to reopen this bugzilla if you are able to reproduce it. |
