not booting after upgrade from 20.04 to 22.04

us flag

I have tried twice to upgrade my existing Ubuntu 20.04LTS to 22.04LTS. Both times I have had the same issue. The upgrade appears to go fine but when I reboot I get:

Gave up waiting for suspend/resume device
Gave up waiting for root file system device.  Common problems:
 - Boot args (cat /prod/cmdline)
   - Check rootdelay= (did the system wait long enough?)
 - Missing modules (cat /prod/modules; ls /dev)

My system is a dual boot with Windows 10 using dmraid and mdraid. dmraid on the boot drives.

Here is lsblk -f using sysrescuecd. You can see that the UUID does exist on /dev/sda5, /dev/sda6 and pdc_bgbgibebbp5.

My fix has been to restore my boot partition back to 20.04 using partimage. I would really like to get this working. Any help would be appreciated.

Thanks

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.
