Hi, I have been trying to install Ubuntu 18.04 on my laptop (Dell Inspiron 7490), but this bug has been preventing me to do so. Unfortunately, there is no AHCI option in the BIOS of this laptop. I spoke to Dell's Technical Support team and it seems like they won't support AHCI in future BIOS updates. Does it mean it's impossible for now to install Linux on this and possibly other new laptop models? If so, is there any hope for this bug to get fixed in the near future? I understand, that lack of progress on this issue is caused by lack of documentation from Intel.
