Can't suspend system when Noapic parameter is active

[RokiP]

I have a new laptop (Acer Aspire A315-41).
I had a lot of trouble installing Linux Mint (and other distributions) but when I finally managed to, the system was very slow and one CPU thread was constantly under heavy load.
I added "noapic" to the kernel options and that seemed to solve that problem completely, but now I cannot suspend the system. If I do so from the OS or by closing the computer, the screen goes black, but the fans keep spinning and after that, I can't "wake it up". I must completely turn it off and on again.

Is there a way to be able to suspend the system with "noapic" enabled?
Or is there another possible solution for my slow system?

I scrolled through the list of possible boot parameters and tried some of them that I thought could be related, but I don't really know what I'm doing and had no success.

Thank you for your help.

...i assume that your laptop is one of those ones?
Post an inxi -Fxz report for people around to have a more exact idea.

...also, have you've already seen this bug report here?
If not, can you try out the parameters / 'workarounds' suggested there?
(ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 instead of noapic)?

[RokiP]

I already added those two parameters, as I couldn't even boot without them (I used 00:00.1 instead of 00:00.2, but after I tried both and I didn't see a difference). OS works without "noapic", but it's slow and laggy.

[thx-1138]

Rokip, i'm afraid with it being that new...you'll have to wait...as you see, it's still being worked upstream...

[RokiP]

I did some more testing.

I installed Ubuntu and the results were the same as on Mint.

I tried Debian, which managed to boot with default parameters, but still printed out the familiar "AMD-Vi: IOAPIC[] not in IVRS table". Adding "noapic" or remapping addresses with "ivrs_iommu[]=" solved that problem, but in any of those cases, I couldn't wake the system.

Lastly I tried Fedora. Again, it booted with default parameters and again printed the same error. But this time, after I added "ivrs_ioapic[4]=00:14.0" and "ivrs_ioapic[5]=00:00.1", i could suspend the system and wake it up no problem. Both from the UI or just by closing the lid.

Linux fedora had kernel version 4.16.3. Linux Mint kernel version was 4.14.0. I forgot to check with Ubuntu and Debian.
I'll try to update the kernel, but if it works with Fedora, I assume it could work with other distros too.

...RokiP, you'd need a cutting edge distro to get all stuff working properly on that laptop, and even then,
as seen above, not even with current 4.18.x things have been ironed out...expect glitches here or there.
It will take some time for things to be sorted out.
I'd prefer the ivrs_iommu remapping than the noapic parameter myself (assuming it does the trick by itself),
as the latter will have quite a bit of a performance hit.

...if you insist / prefer Mint 19 (personally, i wouldn't with that laptop until 19.1 came out...
i'd use Fedora as you already did above, or maybe say Manjaro), a good way to try out Canonical's 4.18 is provided here:
viewtopic.php?p=1521382#p1521382
Or you could try out the mainline series...

Fedora looks nice, but I'm really bothered by the lack of minimize button. Anyway, this will be my first Linux computer and I need something beginner friendly. I did have a bunch of problems with this laptop. Perhaps updating BIOS would also be worth looking into.

Anyway... we'll see if updating kernel fixes anything.

[RokiP]

Nope.
I tried kernel versions 4.16.3 (same a Fedora) and 4.18.10 (currently latest version).
In both cases, I didn't notice any differences and I still either have no sleep functionality with 'noapic' or terrible performance without it.
