Public bug reported:
Hello all,
Ubuntu 21.10 on RPI4 and Kernel 5.13 broke my system when 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,
