Lenovo 14ACH5 - ACPI Error on boot

PvdL

I can't boot normally anymore... It's stuck at the Lenovo logo in boot. When quiet splash is removed I can see the error below.

I still can boot by setting nomodeset after quiet splash but that does mean I can't even control the brightness of the screen.

Now I booted to Windows (instant regret), updated the BIOS, reboot, UEFI partition f'ed (even more regret for booting the MS crap), created and booted usb stick, fixed uefi, reboot and still same sh!t...

ACPI Error: No handler for Region [ECSI] (00000000ae16787e) [EmbeddedControl] (20210730/evregion-130)
ACPI Error: Region EmbeddedControl (ID=3) has no handler (20210730/exfldio-261)
ACPI Error: Aborting method \_SB.UBTC.ECRD due to previous error (AE_NOT_EXIST) (20210730/psparse-529)
ACPI Error: Aborting method \_SB.UBTC._DSM due to previous error (AE_NOT_EXIST) (20210730/psparse-529)

This happens with multiple kernel versions, defaults that come with Ubuntu 20.04, 5.11 but also with 5.15

OS:

  • Ubuntu 20.04.3 LTS

Hardware:

  • Lenovo Yoga Slim 7 Pro 14ACH5 - 82MS001TMH
  • AMD Ryzen 7 5800H
  • Radeon RX Vega 8
  • Intel Wi-Fi 6 AX200 (I replaced the (horrible) Realtek RTL8852AE)

This feels wrong but upgrading to Ubuntu 21.04 fixes it... calling this a solution feels wrong...

I have been unable to determine what causes the error, it doesn't seem to be a kernel version and I was unable to switch/downgrade `acpid` versions

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.
