I tried swapping different setups that I have, I've now tried it with two different firmware versions, one from May and the other from 6th of July (which is the most current version). It's either the "cursor of doom"-screen (on two of the Xubuntu desktop installs) or the "rainbow screen of death" (on the fresh 64-bit Ubuntu Server).
On the one that boots into the blinking cursor, none of low level boot bypass keys work. The disk utilization led stays. RPiOS and other OS's work just fine, and both of those systems that had been working previously, had been running without much troubles since 21.04 hirsute came out. Please advice, as, like I just noticed, this has the possibility to affect every single user installing the 5.11.0.1015-raspi update from the apt packages. I'd need all the help restoring my bootloader to those two of my systems, they worked perfectly well and I wouldn't want to ditch and rebuild them. :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1937924 Title: kernel upgrade via apt 5.11.0.1015-raspi kills the OS on Raspberry Pi4B To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta-raspi/+bug/1937924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
