(The original reporter posted this in a new bug when it was probably meant as a response to this one):
You were right to question this — I confirmed with dpkg -S that the Kabini microcode files belong to linux-firmware-amd-graphics, not linux-firmware-misc, and that package was not touched that day. I also checked /var/log/dpkg.log more carefully and found that linux-firmware-misc was the only package that changed. However, I noticed that both the original upgrade AND my later downgrade each triggered a dracut run (regenerating the initramfs). This suggests the actual fix may have been the initramfs regeneration itself, not the specific package version. I likely had a stale/corrupted initramfs that got refreshed as a side effect of any package change triggering dracut, unrelated to the firmware content. I'd suggest this bug may not be a real linux-firmware-misc regression — apologies for the false lead. Happy to test further if useful, e.g. running update-initramfs -u without changing the firmware package version, to confirm. Si tu veux vraiment clore la question proprement, tu pourrais faire un test propre : remets 0ubuntu2.2 (sudo apt-mark unhold linux-firmware- misc && sudo apt install linux-firmware-misc), puis lance juste sudo update-initramfs -u sans changer la version, redémarre, et regarde si le problème réapparaît ou pas. Ça confirmerait ou infirmerait l'hypothèse dracut de façon définitive. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2163268 Title: linux-firmware-misc 0ubuntu2.2 causes screen corruption at boot on AMD Kabini (radeon driver) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2163268/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
