Ubuntu 20.04 5.11.0-40-generic => ALERT! UUID=... does not exist!

After auto updating the kernel from 5.11.0-38-generic to 5.11.0-40-generic my system won't boot My computers are

  • Apple Mac mini 2019 (Intel(R) Core(TM) i7-8700B CPU @ 3.20GHz) and Apple Macbook pro 2019
  • Linux is installed on a "WD My Passport SSD 500 GB externe SSD" on partition /dev/sda2

The problems occur with both systems. I have tried to boot with a fresh installation Ubuntu Desktop 20.04.3. It ships with kernel 5.11.0-27. After Updating to 5.11.0-43 the same problem occurs.

I get following error messages:

Begin: Waiting for root file system ... Begin: Running /scripts/local-block ... done.
done
Gave up waiting for root file system device. Common problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
 - Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=e373b7f7-deb5-4265-9699-f36a857daeb9 does not exist. Dropping to a shell!
...

As described I tried to set rootdelay=90 in rEFInd boot options editor. But this doesn't fix the problem.

EDIT: It seems that there is no access to the external drive.

(initramfs) cat /proc/cmdline
ro root=UUID=e373b7f7-deb5-4265-9699-f36a857daeb9 initrd=boot\initrd.img-5.11.0-40-generic

When I boot the system with kernel 5.11.0-38 the output of blkid looks like

sudo blkid

Please add the output of the commands: cat /proc/cmdline and of sudo blkid to your original posting. Is the UUID used in cmdline the one in your error message (that would be from your /boot/grub/grub.cfg)? Another place the sda2 UUID is used is the 3 line stub grub.cfg file in /boot/efi/EFI/ubuntu.grub.cfg -- is that one correct?

Last week the auto updater installed kernel version 5.13.0-27-generic and everything is working again. Unfortunately I still don't understand what happened.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
