Debugging _usr_bin_gdb.0.crash

Hi, my kernel crushes and I have the following core file:
/var/crash/_usr_bin_gdb.0.crash

And I cant debug it via gdb:

root@ingame:/var/crash# gdb _usr_bin_gdb.0.crash

Any help is greatly appreciated

I have never used this, but can you say more about the original error, and if it is reproducible? Did the system itself fail? What was running? Are you using a modified kernel? When this occurs is there any note of it in “dmesg” (you could run “dmesg --follow” in a serial console before the condition occurs if there is an issue trying to get logs).
