The tradeoff of disabling hybrid graphics is that, with discrete nvidia
graphics only running, I lose all power management, screen power off,
and suspend/resume support (because suspend works, but after resume
video does not come back).
Since I'm now at a sprint, these are bigger practical issues
The system has now been running stably for 6 days, which is an order of
magnitude better than what I was experiencing since filing this bug
report.
I will at some point flip the firmware setting back to see how it
behaves. Are there any other tests I should try?

Before I had a chance to try uninstalling the nvidia driver, the laptop
crashed again, and then I was unable to get it to boot across multiple
(10+) attempts. After catching kernel output on one hung boot (by
pressing Esc to clear plymouth), I was able to see that the hardware
hang happened right
Could you uninstall nvidia-driver to narrow down the scope of root
cause?

I've also tried upgrading to a newer shim, in case something left around
in memory was causing problems. This also didn't help.
And quoting the kernel error here for text searchability:

Have upgraded to 5.11.0-33-generic from hirsute-proposed; hang still

Would you expect disabling Secure Boot to have an effect here? It should be
out of the way after the kernel has booted.
I have disabled Secure Boot, and the hang is still reproducible.

Hi Steve,
Could you try disabling Secure Boot in BIOS?

Have upgraded the firmware, but the intermittent hang is still
reproducible. I'm attaching updated apport data after the firmware
update.

Problem has also reproduced, with both 5.11.0-16 and 5.11.0-25, using a
downgraded nvidia stack.
Will now look at upgrading the firmware as suggested to see if that
helps.

I have downgraded to 5.11.0-16 and the problem is still reproducible. I
am now going to attempt to downgrade the nvidia driver to confirm that
it's not reproducible with the previous version.

Hi Steve,
#8 looks that NVIDIA and ACPI are related.
BIOS N2OET40W is a bit old, would you mind update it:

I managed to catch a hang while at console on shutdown of -25. Photo
attached of the last kernel output before the hang.
Similar behavior was seen with 22 and current Nvidia.
Now booted to 16 to see if the problem follows.

I'm not sure that I have the same problem.
But on a Dell Precision 7530 with kernel 5.11 I get a black screen and nothing
works.

Nvidia Quadro P3200
This happens on Ubuntu 21.04 or Ubuntu 20.04 with kernel 5.11.
But I can boot usb live in failsafe mode with
If you want to try going back to 5.11.0-16-generic, you can install the
nvidia-dkms-$flavour package for your NVIDIA driver, and, assuming you
are using secure boot, let DKMS enroll its own key.

I didn't reproduce this issue on another X1 2nd.
Reboot for 10 times, all good.

I probably would first suggest to try the proposed 5.11.0-26 from this
cycle. The other path which might be useful (but I do not know whether
this is possible with the HW) would be to attempt a bit with the nouveau
driver. That might separate whether this is in Nvidia or the kernel.

Could you try 5.13 or 5.14 kernel combined with nvidia-driver-465/470?
And upload the log when hang.
