--- Comment #21 from Francisco Pina Martins f.pinamartins@gmail.com --- Created attachment 139288 --> https://bugs.freedesktop.org/attachment.cgi?id=139288&action=edit journalctl log with KASAN_OUTLINE and kasan_multi_shot using a kernel compiled with debug info
Ok, so here's what I did. Since I did not have space for the kernel with both KASAN and debug info enabled (the 590Mb was already with CONFIG_DEBUG_INFO_REDUCED), I got my hands dirty and used nconfig to strip a ton of drivers I was pretty sure I didn't need from the build (stuff like nouveau, industrial controllers, game-pads, etc..). I got the kernel down to ~390Mb which was enough to install. I have attached the journalctl log file with this new kernel (linux-kasan-debug-stripped). As for faddr2line output, here is the original command with the new kernel:
``` francisco@ZenBox [23:09:51] [/usr/lib/modules/4.16.5-1-kasan-debug-stripped/kernel/drivers/gpu/drm/amd/amdgpu] -> $ /usr/lib/modules/4.16.5-1-kasan-debug-stripped/build/scripts/faddr2line amdgpu.ko firmware_parser_create+0xa70/0xd90 firmware_parser_create+0xa70/0xd90: get_integrated_info_v11 at /tmp/build/linux-kasan-debug-stripped/src/linux-4.16/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:1572 (inlined by) construct_integrated_info at /tmp/build/linux-kasan-debug-stripped/src/linux-4.16/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:1714 (inlined by) bios_parser_create_integrated_info at /tmp/build/linux-kasan-debug-stripped/src/linux-4.16/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:1755 (inlined by) bios_parser_construct at /tmp/build/linux-kasan-debug-stripped/src/linux-4.16/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:1912 (inlined by) firmware_parser_create at /tmp/build/linux-kasan-debug-stripped/src/linux-4.16/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:1927 ```
And here is the "new" command with the new kernel:
``` francisco@ZenBox [23:10:27] [/usr/lib/modules/4.16.5-1-kasan-debug-stripped/kernel/drivers/gpu/drm/amd/amdgpu] -> $ /usr/lib/modules/4.16.5-1-kasan-debug-stripped/build/scripts/faddr2line amdgpu.ko firmware_parser_create+0xa9b/0xd90 firmware_parser_create+0xa9b/0xd90: get_integrated_info_v11 at /tmp/build/linux-kasan-debug-stripped/src/linux-4.16/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:1574 (inlined by) construct_integrated_info at /tmp/build/linux-kasan-debug-stripped/src/linux-4.16/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:1714 (inlined by) bios_parser_create_integrated_info at /tmp/build/linux-kasan-debug-stripped/src/linux-4.16/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:1755 (inlined by) bios_parser_construct at /tmp/build/linux-kasan-debug-stripped/src/linux-4.16/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:1912 (inlined by) firmware_parser_create at /tmp/build/linux-kasan-debug-stripped/src/linux-4.16/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:1927 ```
This is no longer a "franken-kernel-mosnter", does this output reveal anything new?
