This bug effects me. Raspberry Pi 4b 8G 5.1V 5A power supply. This RPi + power supply has worked for a long time with raspiOS.
put ubuntu 24.04.2 lts image on sd card with rpi-imager. add 'nomodeset' to cmdline.txt. Power on. after a long time, some activity and desktop setup started. TZ, keyboard, wifi setup completed. After some time, a logo semi compass rose ? appeared. some time later, the screen blanked and became solid blue. some time later, the screen changed to black. After 30 minutes, I powered off, wait 30 sec, power on. The green led blinked several times then was solid on. A rectangle with retangle with colors appeared. some time later the screen blanked. After 10 minutes with no activity,I cycled power again. The green led blinked several times then was solid on. A rectangle with retangle with colors appeared. An orage circle with three dots appeared at the top of the screen. A microsoft-like activity circle in the middle. 20 years ubuntu at the bottom. Aftrer 12 min, pressing some keyboard keys and movine the mouse, I think ctrl-alt-reset caused a power cycle (?) the red led blinked and the process started again. The logo, activity, ubuntu screen appeared. the green led flashed briefly several times at about 10 second intervals. removed nomodeset from cmdline.txt power on red/blue/yellow rectangle blank screen - green led flashed several times The logo, activity, ubuntu screen appeared. the green led flashed briefly after 10 minutes, gave up. put raspi OS on the sd card with rpi-imager. power on - all OK. repeated install desktop image on sd card added 'enable_uart=1' to config.txt connected serial adapter to rpi and started gtkterm ttyUSB0, 115200 Power on rpi booted to the logo, activity, ubuntu screen NO TEXT ON gtkterm. This same sequence with raspiOS had boot text on gtkterm. use rpi-imager to put 24.04 lts on new sd card added 'enable_uart=1' to config.txt Power on rpi booted to the logo, activity, ubuntu screen crown logo lang, kbd wifi+pwd tz account+pw configuring ... account, hardware, etc. crown logo applying changes ... screen blanked, boot-like log appeared ... 474.066902 kernel panic - not syncing: oops: fatal exceptin in interrupt ... 475.124457 SMP: unable to stop secondary cpus 0-3 ... 475.154664 unable to handle kernel paging request at virtual address ffff0414401ce21c ... 475.160560 [ffff0414401ce21c] pgd=0000000000000000 p4d=0000000000000000 system frozen Looking at the sd card on another computer, on my system, sdb. in the root directory of sdb1, I find a core file > sudo file core core: ELF 64-bit LSB core file, ARM aarch64, version 1 (SYSV), SVR4-style, from '/sbin/init fixrtc splash', real uid: 0, effective uid: 0, real gid: 0, effective gid: 0 Tom Dean -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065367 Title: 24.04 LTS Installation failed on RPI5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/2065367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
