I recently bought an HP 17-cb0011nv laptop and I was trying to install Linux on it. I tried to install several distros on it, like Ubuntu 18.04, 19.04 and even 19.10. The installation process was very buggy and after multiple tries I was able to install all of the above versions of Ubuntu. But none of them were stable. During the startup sequence the most frequent outcome were either a blank screen or the splash screen running indefinitely.

When on the splash screen, by pressing F3 I would get a fast never ending scrolling wall of text with ACPI errors. I then tried to boot with ACPI=off from the grub menu and as a result it would crash around 30 seconds of usage or get a kernel panic (more often). After that I tried several other flags like nolapic which seem to work more often (even though the performance suffers greatly). I am seriously very frustrated by this, and I have spent a lot of time already trying to fix it. Do you have any idea how can I fix it?

ACPI errors:

  • You should have used pictures from an on-topic release; 19.10 is off-topic on this site until it's release as it's a development release and bug reports belong on launchpad (and support for 19.10 is not available here). – guiverc Oct 1 '19 at 10:52
  • The ACPI errors were the same on all the versions I mentioned. I don't think that the kernel version matters in this case, since I was getting similar behavior even when I was using "on-topic" releases. – vpap Oct 1 '19 at 11:12

A user from another forum suggested me, to use the boot flag pci=nommconf. This has worked great so far.
