Comment 399 for bug 1776563

Bugs still persist with bios 1.13 and 5.0+ kernels. Advanced touchpad doesn't work out the box like 4.19 and 4.20 did, new dmesg errors about pcie powersaving [use pcie_aspm=off to fix], complaints about not locating smbus and iommu too late in the boot (sometimes causing softlocks [fix with Ives args]), and acpi tables not all loading [11 successful]. These bugs persist, so should not be closed. I think someone with some handy bios skills should look at what Lenovo and HP have done with their bioses vs ours as their MBs [same] work well now. It's been over a year since these computers have been on the market without much in the way of Linux compatibility. I doubt Acer will bother to debug correctly as it works with Windows and that's the only thing they're concerned about supporting, unfortunately. If we close this bug report, then we all might as well give up on these machines.
