"Fixing recursive fault but reboot is needed" on Mint 20.1 / Lenovo

[lanet]

I recently installed Linux Mint 20.1 Cinnamon (64-bit). I get the error quite often when I shut down the laptop, then I have to forcefully shut down by holding the power button. I once tried to wait for 2-3 hours, but since nothing seemed to change or fix, I had to force shutdown.



What is causing this problem and how can I resolve it?

Hi lanet. That is a pretty clear picture there, but I don't see an obvious error. If you do, please point it out.
Since your machine is not shutting down properly, I suggest you restart the computer after you see this problem and type this in a terminal:

Code: Select all

journalctl -rb -1 | nc termbin.com 9999

The command prints the journal log information of the prior boot cycle in reverse order (which means whatever the problem is will be near the top) and sends it to termbin.
It will return with a url address that you should post here.

It's a stack trace from a crashed radeon kernel driver. We're going to need the output of inxi -Fxz for this.

We need you to post the output from a terminal command:

inxi -Fxz

Post the output back here using copy/paste. Before you paste the output, click the </> icon, which only appears when you reply. Paste your output between the [code] and [/code] tags to make it readable.

[code]It should look like this[/code].

Thanks to both of you in advance

OK, so the guy who still doesn't know what an strace is will jump right in and fix the problem

Perhaps we should go to the Driver Manager and see what is available there. I also am wondering if you have ever tried the 5.8 kernel.

Perhaps we should go to the Driver Manager and see what is available there. I also am wondering if you have ever tried the 5.8 kernel.

In driver manager, I have a Realtek Semiconductor Corp. device named rtl8812au-dkms.

I have never tried 5.8 kernel. Do you suggest me to install the 5.8.0-45 version and see if the problem persists?

BTW, I haven't encountered the problem for about 2-3 days, though I didn't change anything important in particular.

[mikeflan]

I'm a bit surprised you don't have graphics driver options in the Driver Manager, but I know very little about Realtek or Radeon graphics cards.

If your system is shutting down OK, I would not upgrade the kernel. Maybe wait until it fails again.

I think I see 2 graphics devices. If the problems return I would try to turn one off in the bios.

When something crashes (in this case the radeon graphics drivers), a stack trace is created by the system to help developers determine what happened so it might be fixed.

I'm perplexed as why you would "jump right in" when you do not understand the problem.

I'm a bit surprised you don't have graphics driver options in the Driver Manager, but I know very little about Realtek or Radeon graphics cards.

The graphics drivers for Radeon (AMD) are in the kernel. They install when the system boots. They are never in Driver Manager.

[SMG]

In driver manager, I have a Realtek Semiconductor Corp. device named rtl8812au-dkms.

RTL8812AU: 802.11ac/abgn USB WLAN Network Controller

I have never tried 5.8 kernel. Do you suggest me to install the 5.8.0-45 version and see if the problem persists?

I do not see any reason at this point to try the 5.8 kernel. Your system is not even currently rendering with the Radeon card.

You followed the advice given in the title of the thread and rebooted.

Code: Select all

Mar 09 20:23:36 lanet kernel: Fixing recursive fault but reboot is needed!

I am going through the log and will let you know what I find.

That is the url generated right after the problem occurred.

What problem did you see occur? I ask because this appears to be a boot cycle where the desktop ran for about two minutes before you shut down. Did you shut down because there was an issue?

I did see this:

Code: Select all

Mar 09 20:20:15 lanet kernel: acpi MSFT0101:00: platform device creation failed: -16
Mar 09 20:20:15 lanet kernel: platform MSFT0101:00: failed to claim resource 1: [mem 0xfed40000-0xfed40fff]

but the third answer in this thread Can't load, failed to claim resource: 1 indicates it's the TPM (trusted platform module) which I would not expect to be related to this issue.

The following happened during start-up:

Code: Select all

Mar 09 20:20:28 lanet kernel: [drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed (scratch(0x850C)=0xCAFEDEAD)
Mar 09 20:20:28 lanet kernel: [drm:si_resume [radeon]] *ERROR* si startup failed on resume

This seems to be a PCI related issue according to what I can tell from this bug report Bug 196197 - [drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed (scratch(0x8504)=0xCAFEDEAD) . Someone at the bottom posted within the last year indicating the issue with what appears to be the same graphic cards as what you have. This could be one of those issues which was resolved, but returned. It seems it only affected certain boards.

The system was already in the midst of the shutdown then this seems to precede the radeon crash:

Code: Select all

Mar 09 20:23:35 lanet kernel: BUG: kernel NULL pointer dereference, address: 0000000000000000
Mar 09 20:23:35 lanet kernel: #PF: supervisor read access in kernel mode
Mar 09 20:23:36 lanet kernel: #PF: error_code(0x0000) - not-present page
Mar 09 20:23:36 lanet kernel: PGD 0 P4D 0 
Mar 09 20:23:36 lanet kernel: Oops: 0000 [#1] SMP PTI

I do not have any ideas at the present time what might clear or prevent the issue from happening.

BTW, I haven't encountered the problem for about 2-3 days, though I didn't change anything important in particular.

Do you normally run with the laptop plugged in or just on battery? Might there be a correlation between whether it is plugged in or not as to whether this happens?

What problem did you see occur? I ask because this appears to be a boot cycle where the desktop ran for about two minutes before you shut down. Did you shut down because there was an issue?

Nope, there was no issue, I consecutively tried to reboot so the problem about "Fixing recursive fault but reboot is needed" would occur.

I normally have laptop plugged in. To be honest, I have not contemplated the correlation but will give it more attention when this happens again.

[mikeflan]

I'm perplexed as why you would "jump right in" when you do not understand the problem.

lanet PM'ed me and asked that I respond. I chose to make the joking comment in the forum, which only he would fully understand. You are right. I am clueless on this.

I'm having the same issue with my Lenovo laptop on Linux mint 20.2. I have a Radeon and Intel integrated graphics card. Have you been able to solve the issue?

If you do not have the exact same laptop (with the exact same hardware), please create your own thread for your issue and make sure to supply the information requested in Section 5 of READ: How To Get Help! in your first post in that thread.

I do not have the exact hardware but the issue is the exact same including the error log. So I am just wondering if he was able to solve the issue in anyway ?

[SMG]

I do not have the exact hardware...

Hardware can definitely make a difference to solving issues. Please create a new thread for your issue.
