Confirmed this on noble. The root cause is an older boot EEPROM
(specifically Dec 2023). On the older firmwares it appears the
bootloader pre-allocates a framebuffer with an incorrect resolution for
the DSI display, and (on the server images at least), the kernel
attempts to re-use this framebuffer which fails. The newer bootloader
(tested June 2024, and Dec 2024) honours the disable_fw_kms_setup=1
setting in config.txt, leaving the kernel to handle display setup, which
it does correctly.
Ultimately, this is a duplicate of LP: #2085903 which, once it lands,
will update the EEPROM image to June 2024. This is already fixed in
plucky (devel) which has the later package. Marking accordingly.
