** Description changed: After writing the Ubuntu 24.04 Desktop for Raspberry Pi image to an SSD drive with a USB3 interface (specifically; this issue does not occur when booting from an SD card), booting the drive on a Pi 4 or Pi 5, and running through the installer to the point where the (corrupted) slide deck starts to display during setup, the installer crashes. [ Workaround ] - This is a temporary fix, confirmed on a Pi 4 (would be grateful if - others can confirm the workaround on a wider variety of hardware). + At the time of writing, some workarounds have been found, but none that + consistently work on all boards with all drives. One workaround that has + worked on a Pi with a Samsung EVO SSD, and a Crucial SSD is as follows: + Before booting the image, find config.txt on the boot partition, and the "dtoverlay=vc4-kms-v3d" line within it. There will be two of these lines, you want the first one under an "[all]" section. Append ",cma-128" to the line. Specifically, the following section: - dtoverlay=vc4-kms-v3d - disable_fw_kms_setup=1 + dtoverlay=vc4-kms-v3d + disable_fw_kms_setup=1 Should become: - dtoverlay=vc4-kms-v3d,cma-128 - disable_fw_kms_setup=1 + dtoverlay=vc4-kms-v3d,cma-128 + disable_fw_kms_setup=1 Unmount the drive cleanly, boot it, and run through the installer. You may revert the change (if you wish) after successful installation. + + Another workaround, reported as working on a Pi 5 with an NVMe drive + attached over PCIe: + + Before booting the image, find config.txt on the boot partition. Under + the first "[all]" section append the following line: + + dtparam=pciex1 + + Unmount the drive cleanly, boot it, and run through the installer. + + Please note both workarounds have also been reported as failing with + certain drive combinations. [ Background ] Given this crash occurs immediately upon the (corrupted) slide deck starting, that it only occurs when booting from USB (but the exact same image works from an SD card), and that merely changing the pre- allocation of the contiguous memory area affects it, I suspect this at least related to (if not a duplicate of) LP: #2037015, particularly since a crash bug is now associated with it too, LP: #2062146. Still, I'll leave this open as a non-duplicate for now as I'm not positive of root-cause yet.
