[Bug 2158932] [NEW] Black screen on boot with Linux Kernel 6.8.0-134.134

Public bug reported: Using Linux Mint with Linux Kernel 6.8.0-124 with no issues. Update Manager showed new update for Linux Kernel available, version 6.8.0-134.134. Installed update and restarted system as instructed. Chose to launch Linux Mint from Grub boot menu (dual boot system with Windows 10), black screen results after selection, no splash screen, nothing. Reverted to Kernel 6.8.0-124 successfully via Timeshift from Linux Mint USB boot disk. Reattempted update to Kernel 6.8.0-134.134, same result: black screen after boot selection. Again reverted backto Kernel 6.8.0-124 successfully via Timeshift from Linux Mint USB boot disk. I have a second system (dual boot Linux Mint/Windows 10) with a similar hardware configuration but with an older Radeon RX580 that I was able to upgrade to Kernel 6.8.0-134.134 successfully. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Attachment added: "lspci-vnvn.log" https://bugs.launchpad.net/bugs/2158932/+attachment/5979790/+files/lspci-vnvn.log -- You received this bug notification because you are subscribed to linux in Ubuntu.
