Karabiner-elements: M1 Mac Mini Kernel Panic on Restart
On machine restart, the dock hiding animation freezes midway, which to me indicates a hang. On booting back to desktop, the crash reporter appears with the below text. I cut off the long list of loaded kexts but can provide those if needed.
panic(cpu 6 caller 0xfffffe0025cf84d0): "pmap_tte_remove: non-zero pagetable refcount: pmap=0xfffffdf0459337a0 ttep=0xfffffdf0bd7f8410 ptd=0xfffffdf31897a998 refcnt=0x1"

Since Karabiner-Elements v13.0.0, it is now not related with kernel.
Thus, the panic is caused by a macOS issue.

I understand what you are saying, but I do want to mention that the problem appears after installing karabiner, and resolves after uninstalling. I have done this twice to confirm.

In that case, I guess that Karabiner-Elements triggers an issue of some other incompatible third-vendor apps with Big Sur (e.g., anti-virus software), and the issue causes kernel panic.

I am also experiencing kernel panic when restarting my M1 MacBook Air (see #2517) and uninstalling Karabiner Elements seems to be the only way to fix it. I don't have any anti-virus software installed. Actually my first thought was that Dropbox and iStatMenu might be the cause as those are not yet fully compatible with M1 Mac, so I uninstalled them but the issue persisted. Then I uninstalled Karabiner-Elements, which fixed the issue. The issue did not reemerge after installing Dropbox and iStatMenu again.

Same issue for myself - on a fresh setup, no issue without Karabiner, kernel panic with.
Does anyone have an M1 Mac with Karabiner and not getting the kernel panic on reboot? (i.e. when you reboot, it doesn't show "your computer restarted because of a problem" after logging in). Hopefully we can narrow down who all this is affecting

I get the same issue on my M1 Mac Mini.
macOS Big Sur 11.0.1 (20B29)
Karabiner-Elements 13.1.0 / 13.1.1 beta
I have not yet installed most of the software other than the OS pre-installed.
If you have Karabiner-Elements installed, your Mac will reboot immediately after the system exits (after the power LED is turned off), even if you have Quit Karabiner before the system exits. In this case, there will be no startup sound.
After the automatic reboot, you will get an error report "your computer restarted because of a problem". Considering the lack of boot sound and the error report, it seems that the kernel panic occurred before the exit sequence was completed, which led to the automatic reboot.
If you uninstall Karabiner-Elements, there is nothing wrong with it and your Mac will turn off.

I just set up my Mac Mini M1 and am getting the same error message.
Seems to consistently be triggered upon restart/shutdown. If I quit the app before shutting down, it still happens. My Mac was a migration tool setup from a 2013 15” MacBook Pro.

I have the exact same issue with my MacBook Air M1 + Big Sur 11.0.1. Every time I shutdown or restart my MBA, I get a pop up after booting up and logging in saying "your computer restarted because of a problem". I don't have any issues if I uninstall Karabinar Elements, so I'm pretty sure this app is the culprit.

Just a me too on this with 11.0.1 + Mac Mini M1.

Same here :( Must use Karabiner Elements as I use a PC keyboard and want to invert Command/Alt..

I spent 2 hours checking my system with disk utility, removing Docker, Virtualbox and all software I thought could be the source of this crash, ended up being my lovely Karabiner Elements I use for years to remap Command and Alt. I confirm removing it fixes the issue, and I now use instructions available at https://superuser.com/questions/80976/how-to-re-map-command-and-option-keys-on-mac-os-x-with-a-pc-keyboard and MacOS settings to remap those, you can choose which keyboard you want those change on so I guess even laptop users will be happy.
So long Karabiner, I liked you before! :)

To confirm this is still happening with macOS Big Sur 11.1 (20C69) on a MacBook Pro (13-inch, M1, 2020).
I was hoping it might have been addressed by a macOS update, but not yet. Removing Karabiner Elements results in a clean reboot, reinstalling it results in a kernel panic on every shutdown.
The kernel panic did not affect the install of the 11.1 update either.

To be clear, you shouldn’t have to uninstall Karabiner. Everything works correctly. It kernel panics at the very last step of restart and if you really want to shutdown but it keeps rebooting, click shutdown from the login screen.

If I don't uninstall Karabiner, I cannot shut down my Mac since it always restarts after the LED indicator goes off. Even clicking shutdown from the login screen won't shut down the Mac, it keeps restarting.

Same issue. Only thing that works for me is logging out first, then shutting down from the login screen.

Since Karabiner-Elements v13.0.0, it is now not related with kernel.
Thus, the panic is caused by a macOS issue.
However, this IS the Karabiner issue, for so many people has proved that this crash happens and ONLY happens when Karabiner is installed on M1 Mac.

@windless0530 thanks for the suggestion. I've tested my environment with your solution.
However, it seems we cannot set modifier in detail with Hammerspoon, such as 'right command', 'left command', or 'right option', etc.
Are there more tricks or solution for this case?
BR.
