    Kernel 5.13 broke my Ubuntu 21.10 on RPI4 8Gb

    Hello all,

    Ubuntu 21.10 on RPI4 and Kernel 5.13 broke my system only if I use a USB SSD install.

    Lets see all steps:

    I downloaded Ubuntu 21.10 desktop img from ubuntu daily builds and installed it on a USB SSD (about a month ago).

    Every things were all wright an for me it was better than 21.04. I was very happy.

    Until last week, when Update manager came with a kernel 5.13 version. As usual I applied all updates and rebooted.

    Reboot took a long time and terminated in a character screen and was written Busybox..... initram... Type help for... For what??? I simply didn't know how to deal with that info.

    Than I decide to install Ubuntu 21.04, but firefox latest version was 90 and I would be in trouble to recover firefox (90.0.2) data files form 21.10 and use it.

    So I decide to give ubuntu 21.10 another try, and installed it on a SDcard. set up finished lets update it all and reboot. Reboot successfully and than I copied SDcard to my USB SSD using SD Card Copy from Raspberry PI OS.

    Reboot took a long time and terminated in a character screen and was written Busybox..... initram... Type help for...

    Oh my God, expending a weekend to have a 21.10 working....

    New try... Installed 21.10 again on RPI4 on USB SSD but... but in update manager UNMARKed all kernel 5.13 updates.

    Now I am running Ubuntu 21.10 for 3 days but Kernel installed is 5.11.

    I Hope this report could be useful for someone. And waiting for a fix.

    Thanks,

    Not sure what you've expected. 21.10 has not been released yet, and things are expected to break.

    Also, Firefox 91.0.2 is available in 21.04 for armhf: https://packages.ubuntu.com/hirsute-...refox/download

    I expect ubuntu to be fixed until release date.

    But do be fixed someone must know about this crash. I Hope someone of developing team could see this report.

    Knowledge is the Key.

    The developers will not see this. This is not a report.

    The developers do not hang out here. This is a peer-to-peer user support forum.

    Please look here for instructions on how to report bugs.

    I just realized you have this on a Raspberry Pi. Unsure of its architecture.

    The kernel 5.13.0-16 in Proposed will crash. -14 is working ok for me. If you have a separate Home partition you can reformat root on reinstall and all of your installed applications will come back up perfect.
