darp6/galp4 don't boot (proprietary EC only) #12

Closed jacobgkau closed 3 years ago

jacobgkau commented 3 years ago

Distribution (run cat /etc/os-release): Pop!_OS 21.04, Pop!_OS 20.04 LTS, Ubuntu 20.04 LTS

Related Application and/or Package Version (run apt policy $PACKAGE NAME): system76-acpi-dkms version c169971892d4bd0fa8524a86b2da36d990fc1d7b and b82bcba7d90abc99f76f7072e8e31d7b9de64e18

Issue/Bug Description: The system hangs at the firmware splash screen and does not display the cryptsetup screen.

Steps to reproduce (if you know):

  1. Update system76-acpi-dkms on an affected system
  2. Try to boot

Expected behavior: System should boot

Other Notes: Only affects darp6/galp4 running proprietary EC, does not affect systems transitioned to Open EC (only darp6 has Open EC officially released.)

Checked out c169971892d4bd0fa8524a86b2da36d990fc1d7b, built & installed, still had the issue; checked out 0bc966cf8ec11a173e0bdffb9d5df8d99bea2617, built & installed, and did not have the issue. Based on this, it appears the issue is in c169971892d4bd0fa8524a86b2da36d990fc1d7b and not necessarily b82bcba7d90abc99f76f7072e8e31d7b9de64e18.

I don't see any output when pressing ESC at the stuck splash screen, and nothing is being logged to journalctl on affected boots.

Are all the command line options that hide logs removed, like quiet? And try without splash as well.

Ok, after removing all of the log-suppressing options, I'm seeing a kernel panic, but it's scrolling very quickly. I'll need to take a video and go frame-by-frame to see what it says. There are a couple of psmouse serio2: synaptics: lines about the touchpad after the kernel panic.

Does this help?

It looks like a number of items can't be removed:

kernfs: can not remove 'uevent', no directory
...
kernfs: can not remove 'waiting_for_supplier', no directory
...
kernfs: can not remove 'online', no directory
...
kernfs: can not remove 'name', no directory
...
kernfs: can not remove 'phys', no directory
...
kernfs: can not remove 'uniq', no directory
...
kernfs: can not remove 'nodalias', no directory
...
kernfs: can not remove 'inhibited', no directory

I can force it to happen.
