journalctl log with KASAN_OUTLINE and kasan_multi_shot using amdgpu.ko compiled
with debug info

Here you go. journalctl log after booting with kasan_multi_shot and using the
`amdgpu.ko` file compiled with debug info. Now this is a Frankenkernel monster
if I ever saw one.
I have taken the liberty of "grepping" for the pattern, and it seems that
"firmware_parser_create+0xa70/0xd90" is still there.
Thank you for passing this along to the DC folk. Please let me know when a
patch I can test is made available. Also, if you need any more information (or
try something), just ask away.
At the very least, with this bug report I have discovered that the KASAN
enabled kernel boots every time, at the expense of an extra second while
booting. I did not notice any other performance differences between the KASAN
enabled and the stock kernel (was I supposed to?).
Once again, thank you, Michael for your patience guiding me through the tasks.
Next time will be easier. _-)
