Re:T14 AMD, kernel says "ACPI Error: No handler for Region [ECSI]"

I' had a bricked machine due to not resetting the BIOS before a fwupd, so I would suggest you do it anyway. It should take 2 minutes tops to note down your bios settings for reverting them afterwards and it might save you from a world of pain.

Same here... how did you unbrick it :)

 

What I did not get about this is this: If you reset Bios defaults, secure boot is enabled. I did not think that I can then start the update, because Linux won't boot. So I reset during reboot. Apparently that was not the right choice :/

I didn't, I got the motherboard replaced.

I see. We did not have the same issue then. I just needed to add the correct entry in the EFI vars again. But I am still stuck with the old fw version.

 

Anyways: If anybody else winds up not being able to boot from their disk, but finds that booting from a USB thumbdrive works: Mount your partitions from the thumb-drive (in particular efi) and re-install your bootloader (e.g. GRUB). Inspecte efi vars with efibootmgr before and after for good measure.

Confirm 2, 3 on my yoga14s(R7-5800H):

1. ACPI Error: No handler for Region [ECSI]

2. Issue with unstable TSC

3. Battery drain problem

 

And, other found:

ACPI Error: \_SB_.UBTC: failed to evaluate _DSM(0x6)

 

kernel: 5.14.1(stable)

Re:T14 AMD, kernel says "ACPI Error: No handler for Region [ECSI]"

@MarkRHPearson   The same problem also affects the S540-13ARE running the latest BIOS (F0CN32WW) under Linux 5.14.9

 

When booting connected to a dock the following error is logged to dmesg:

 

ACPI Error: No handler for Region [ECSI] (00000000d8528837) [EmbeddedControl] (20210604/evregion-130)
ACPI Error: Region EmbeddedControl (ID=3) has no handler (20210604/exfldio-261)
ACPI Error: Aborting method \_SB.UBTC.ECRD due to previous error (AE_NOT_EXIST) (20210604/psparse-529)
ACPI Error: Aborting method \_SB.UBTC._DSM due to previous error (AE_NOT_EXIST) (20210604/psparse-529)
ACPI: \_SB_.UBTC: failed to evaluate _DSM (0x6)
ucsi_acpi USBC000:00: ucsi_acpi_dsm: failed to evaluate _DSM 2


This will result in the dock not being recognised, along with any connected screens, and the laptop not charging.

 

Unplugging and re-plugging will produce a slightly different error, still complaining about ECSI:

 

ACPI Error: No handler for Region [ECSI] (00000000d8528837) [EmbeddedControl] (20210604/evregion-130)
ACPI Error: Region EmbeddedControl (ID=3) has no handler (20210604/exfldio-261)
ACPI Error: Aborting method \_SB.UBTC.ECRD due to previous error (AE_NOT_EXIST) (20210604/psparse-529)
ACPI Error: Aborting method \_SB.UBTC.NTFY due to previous error (AE_NOT_EXIST) (20210604/psparse-529)
ACPI Error: Aborting method \_SB.PCI0.LPC0.EC0._Q4F due to previous error (AE_NOT_EXIST) (20210604/psparse-529)

 

Usually it takes 3 to 5 attempts (timing issue?) at unplugging and replugging the dock to have it successfully recognise the screens and begin charging.

 

The same errors occur when booting without the dock then connecting, so it's not only an issue at startup. This also seems to be related to USB-C connected screens randomly dropping off and failing to reconnect, even after multiple attempts at reconnecting. Only a reboot will get them to show up again.

 

Any chance we can get a BIOS update for this and the other affected devices? From my research it seems to occur on most of Lenovo's Zen 2 laptops.

Re:T14 AMD, kernel says "ACPI Error: No handler for Region [ECSI]"

2021-11-06, 3:10 AM

I have the E15 Gen2 with a Ryzen 4700U CPU and I am also experiencing a version of this issue.

 

I just purchased a Monitor with a built in Hub, Ethernet, and USB-C power delivery so I could swap between a Work and Personal laptop.

 

If I boot the E15 connected to the USB-C I get video and everything works, Ethernet, any devices connected to the Hub, charging, everything.

 

If I disconnect the USB-C cable to use the other laptop I see these errors in dmesg:

 

ACPI Error: No handler for Region [ECSI] (000000009499594d) [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.NTFY due to previous error (AE_NOT_EXIST) (20210730/psparse-529)
ACPI Error: Aborting method \_SB.PCI0.LPC0.EC0._Q4F due to previous error (AE_NOT_EXIST) (20210730/psparse-529)

 

When I try to reconnect I see these same errors repeated again, and the laptop does not recognize an attached display. Sometimes it recognizes some or all of the USB devices connected to the display hub, other times it does not.

 

Dmesg eventually will start complaining that the USB cable must be bad, but it isn't because it always works after a reboot.

 

I am running Manjaro with kernel 5.14.10. I also tried 5.10.70 and 5.15.rc3. They all behave the same.

 

I confirmed that I am on the latest 1.16 BIOS and the issue remains. Is there an update in the works to fix this issue?

@MarkRHPearson I see the same issue on an E14 Gen3 (AMD 5500U) running Fedora's 5.14.16-301.fc35.x86_64 kernel and the latest BIOS version 1.07. Will this be fixed for the E14 as well?

Hi all,

 

Afraid I can't make any commitments for the e-series, S540 or Yoga14s. Those platforms aren't in our Linux program so I have no levers to pull on to get the changes done.

 

That being said - we did recently get a fix done on one of the e-series so I can reach out to my contacts there and see if they will look at this. Hopefully as the fix was done previously for the T-series it might be easy to port it. No guarantees but I'll put this in the 'maybe' category.

 

I'll see if we can track down the owners for the other platforms but chances there are really low. I've not worked with them before. My recommendation is to feedback to Lenovo support that you are looking for Linux support, especially if you haven't done your 90 day customer survey yet.

 

Thanks

Mark

Thanks a lot Mark! I will add that feedback in the 90 day customer survey. I would really appreciate Linux support given that some versions of the E-series models are sold without OS, which makes them a perfect fit for open operating systems.

Thanks Mark!

 

I didn't realize there was an official linux support line. This is my 4th Thinkpad and I've run Linux on all of them. I never had any real issues before this one.

 

If anything can be done anyway it would be much appreciated! If not, thanks for your efforts.
