Logs of 4 crashes.
Since a while ago I've been constantly getting crashes playing Dota 2. Sometimes the game crashes, sometimes something else crashes, but most of the time the whole kernel crashes.
Unfortunately I cleaned the past logs, but I have four instances in my history (attached). It's very easy to reproduce, I just play for a while, and boom, kernel crash, after which I can't do anything but reboot.
All the instances show a crash in _kmalloc_node after i915_gem_execbuffer2_ioctl.
Driver: Intel Open Source Technology Center Mesa DRI Intel(R) HD Graphics 620 (Kaby Lake GT2) x86/MMX/SSE2
Also, other people seem to be experiencing the same issue: https://github.com/ValveSoftware/Dota-2/issues/1616
That is an issue with the tracepoints. I would double check that the code is compiled correctly, and do a bisect -- if the problem is still evident on a recent kernel.

Let me get this straight: a kernel *CRASH* that people experience in the real world is not a bug?
And you don't consider 4.19.49 to be a recent kernel? A kernel released three weeks ago is not recent?
You ask me to check that the code is compiled correctly... How? Here is the config file:
What am I supposed to be checking in that 9.9k lines long file?
Then you ask me to do a bisect. From where?
I'm sure the people experiencing system crashes will appreciate the fact that you have "resolved" this bug.
