Those error messages about ACPI can usually be ignored if the system boots and works as expected. They are unrelated to the OS. Update UEFI.

Edit your question and show me `sudo dmidecode -s bios-version` and tell me the EXACT make/model # of your computer or motherboard.

Your BIOS is current. Enter your BIOS, note what the crucial settings are, then find/select the "Reset to factory defaults". See if that helps.

I am using Ubuntu 21.04, and I had installed Kernel 5.13, I went back to the original Kernel 5.11 and all the messages went away, I am going to wait for 21.10 with the newer Kernel.

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.
