Yes, git bisecting. You may want to bisect commits related to those raven2_* blobs, which should be much less work to do. It's also possible the fix is actually consisted of multiple commits, so when you locate the first good commit, please cherry-pick it onto Bionic HEAD and make sure if that alone fixes this issue. If not, then we'd need to locate the second one, and so on. Thank you. :)

When it freezes, the mouse is the only thing that works, but the GPU gets completely locked up. Keyboard also gets locked up (even Num Lock doesn't respond). There are no crash reports automatically generated. The logs get corrupted so it's impossible to know what happened. Updating it to a new firmware version fixes all freezes and system stability becomes rock solid. I'm not sure which exactly is the relevant firmware file, but I'm using these: fe5ec673b44d95c686a240a8d138f499 raven2_asd.bin a671f876b7ea6ff9f93dc56e0e147157 raven2_ce.bin be6c5c565ec341ee69f6d99a0ecb109d raven2_gpu_info.bin 5d7b9b404c424c692342cc1408553025 raven2_me.bin 81f2957c4512ec2595bb1dbdc37f52ca raven2_mec2.bin 81f2957c4512ec2595bb1dbdc37f52ca raven2_mec.bin 4d7651ab7fc4dba1abcfaf4a88f40686 raven2_pfp.bin 4ac07f88b9c4aa4fe026be87cb16ceda raven2_rlc.bin ac3a488f651921bc5a21b5a443ee7c23 raven2_sdma.bin 2372175130589c169afc4bc0e0435705 raven2_vcn.bin fe5ec673b44d95c686a240a8d138f499 raven_asd.bin 3e4aeb199a9e1c56a398d5b4ff6a7166 raven_ce.bin b5387b400b0ee4b04565a5179aebb9cd raven_dmcu.bin 052cdc264b228656dff12b95def55c54 raven_gpu_info.bin b16a081785f2f75a6f326ca5ca92113d raven_me.bin 4390c8485f4d4583ae878aa227968a48 raven_mec2.bin 4390c8485f4d4583ae878aa227968a48 raven_mec.bin f69ef2e297e66eb68eecb02540780f4c raven_pfp.bin 0e5fff019103b4cdc5a0366e29411fdd raven_rlc.bin df5f1ef96feade475a9c83451d840bb3 raven_sdma.bin 7e22527c2ef5e9b6e4e871d6ec546848 raven_vcn.bin There's the possibility that I'm wrong and the actually firmware file is not related to Raven Ridge (I doubt it, my usage when it freezes points to being a GPU problem) More specifically I'm using these https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git/tag/?h=20190815 I have been working with these new firmware files for months and no crashes. Yesterday linux-firmware was updated reverting my changes, and it started locking up again.
