Hello everyone, thanks for stopping by 😉

I’m having some problems with an Antergos 4.18 installation on my Acer Swift 3 (SF315-41 🤖) the main one is regarding virtualization.

At first when I booted up the OS I would get this messages:

[Firmware Bug]: AMD-Vi: IOAPIC[4] not in IVRS table
[Firmware Bug]: AMD-Vi: IOAPIC[5] not in IVRS table

And the computer would get frozen between 1 to 3 times a day seemingly at random intervals if I was running a VM.

After digging around I found this SO answer which helped me get past those errors by following the instructions under the title “2. Linux workaround”

I thought the freeze problems were gone after that but yesterday it happened again 😔, I took a look at the output of dmesg and sure enough there is a remaining error regarding AMD-Vi:

AMD-Vi: Unable to write to IOMMU perf counter.

dmesg dumps:

Any help regarding how to fix this issue will be really appreciated 🙏 thanks in advance
