Title:
[Dell G5 5590] lspci freezes computer on Ubuntu 20.0
Tried 5.8.0-43 kernel and didn't work.
I also tried booting Manjaro which uses 5.6.15-1-MANJARO and the issue is
present.
I ended up doing a workaround, compiling an ubuntu kernel with `pci-
stub` as builtin and `xhci-hcd` as a dynamic module. That way I can make
pci-stub bind to the culprit devi
OK, so how about if you install the kernel version 5.8.0-43 in your
system? In order to do that, I suggest you to boot using the Live CD and
use chroot - there are goos instructions here :

The only thing to change is step 6: please run "sudo apt-get install

So, when the system is working fine, before the freeze, can you SSH into
it?
Also, what is the kernel version running in the Live image you're booting
there? This information shows early in the kernel logs...but you can also
collect using the "uname -a" command. I'd like to compare the version o
Seems like everything gets locked, including the kernel.
I tried connecting through SSH but it isn't answering.

Hi Ariel, thanks for the pictures! This is interesting, seems you're
facing a USB host controller breakage, so all your USB devices are
frozen. Can you try something, in order for us to be sure about that?
Please, setup a SSH server [0], and after the freeze, try to connect to
the machine using SSH
This is what happens if I go into the tty and don't do anything. All
screenshots and logs were obtained running with `ignore_loglevel` kernel

Hey !
I'm able to boot and get into a tty. But after a few seconds (even if I
don't do anything) it freezes.
Machine boots fine with the USB stick and running lspci doesn't trigger
a freeze.
Attached is the dmesg log, but it seems to be truncated. I managed to
log into a tty and run `dmesg -w` b
You can see the image contains a few more logs that couldn't be written
to the disk

Hi Ariel, thanks for your report! So, let me clarify: now your system is
freezing on boot, you don't need to run "lspci" to observe the freeze anymore?
Can you try adding "ignore_loglevel" in the kernel command-line on Grub, and
observe the boot progressing? If so, then please take a screenshot/
