I've got some interesting news. I did in fact contact Acer Support and
opened a case. Went from Lvl1 to Lvl2 support, was called a couple weeks
later with a survey about support, I gave my honest opinion, stating
that I don't blame support team as they are limited in what they can do.
Today I recei
I can confirm I also have this issue on an ACER Nitro 5 AN515-42-R5GT.
Ryzen 2500U + RX560X using latest BIOS available v1.08. I'm forced to
boot with noapic whether or not IOMMU is even enabled/disabled using
kernel 4.18.10.
Using 4.19.0rc2 I could get by using the GRUB additions:
i8042.nopnp ivr
the solution ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 iommu=pt
isn't helping me on 4.18 or 4.19. I think the first time I got past the
CPU stuck issue with this was a fluke.
I now have to boot with the noapic option every time or I get "CPU
stuck" over and over.
Any and all assistance would
That's just it, my SMBUS is 14:00.0 and IOMMU controller is 00:00.2 just
like the a315-41g. My lspci -vv output was attached to that post just so
people could see.

I've already contacted Acer support and they give the BS answer "We
don't support Linux". I tell them crappy BIOS doesn't matter whether or
not its windows or Linux. its still crappy bios. I suggested they fix it
upstream and I got the response that they'll send it upstream (I'm sure
they will /sar
Yeah, This rabbit hole just keeps getting deeper. a whole 46 Errors, Log
attached. Some appear like they'd be easy to fix for someone who
understood the language.
I'm confused by ssdt14.dsl compile as it only has one error
ssdt14.dsl 1341: Arg1
Error6126 - ^ syn

Richard Baka, Whenever I attempt to decompile using your parameters,
nothing happens. it doesn't work. I instead get a segfault. I'm
attaching my acpi dump, you're welcome to take a wack at it. in fact,
I'd greatly appreciate it if you would and would explain to me what you
did to get it to decompi

siyia, you're welcome to try it yourself from my ACPIDUMP attachment
earlier. its not as simple as it normally would be. In some cases, it
just causes iasl to segfault.

I still have add ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 to even
boot. Ubuntu 18.10 works great so long as I add those in GRUBs editor
before boot or permanently add to grub.cfg after install. Also, hiding
the AE_ALREADY_EXISTS errors doesn't mean they're gone. Fedora is
experimenting with a
I'll run a test tonight and see if I can get power draw differences at
the wall between windows and Linux. Hopefully when Acer drills this
down, we'll see something that compares pretty well.

you: 4.15 kernel doesn't officially support raven ridge CPUs, so yeah
power consumption is going to be bad. You need minimum of 4.18. Have you
tried ubuntu 18.10 with the IVRS flags added?
