  • I do not think these commands freeze the system. Did you install Nvidia drivers? – Pilot6 Feb 03 '17 at 21:15
  • Some people resolved this by blacklisting the nouveau driver. https://bbs.archlinux.org/viewtopic.php?id=183185 https://bugs.archlinux.org/task/45825 – jay armstrong Sep 28 '17 at 22:56

1. Using lspci to get a list of devices

To make lspci work temporarily, you have different possible options that might work :

  • Check that everything is up-to-date, including non-free firmwares
  • Disable ACPI : add acpi=off to the grub kernel command line (see this thread)
  • Blacklist some well-known drivers, like nouveau
  • Install an older kernel

When you can run lspci, save the bus IDs in a file :

lspci | awk '{print $1}' > pci_ids.txt

2. Debugging devices

Then, reboot "normally", i.e. with the config where lspci was not working before, and run lspci with each id :

for i in `cat pci_ids.txt`; do echo " * CHECKING $i";lspci -s $i; done

Then, you will find which hardware is the source of the problem.

    Worked great, thanks. For me, adding acpi=off to grub options was enough to get a working lspci. (NB: no need to make this permanent as explained in the last step of the linked solution). Then I found nvidia as the culprit and could investigate further – Pierre Gramme Nov 12 '18 at 13:27
