If the pool is on top of LUKS (a relatively common configuration when

siyia, I don't recognize any problem but I'm not sure there aren't any.
That is sure I've broken some functions.

Title:
Darksurf (piroisl33t-u), what you've done is not what I had written.
siyia (siyia), I can send you but this is just a hack not a correct fix. I
deleted lines, forced return values etc etc.

Hi, noapic is not a too sophisticated solution.
Try this:
mkdir bios_sck
cd bios_sck
sudo acpidump -b
A lot of firmware file should be appeared we need SSDT/DSDT dat files
You should decompile all of them but that is impossible because of some
interference between the files.

Is there something inherent in snaps that makes this easier or better
than debs? For example, do snaps support multiple installable versions
of the same package name?
If snaps aren’t inherently better, the same thing could be done with
debs using the usual convention for having multiple versions
For me the latest 4.18 is the best. AMDGPU PRO is not necessary. Please
copy-paste for me the "sensors" output on 4.18 kernel.

I'm glad you did it.
Why does the kernel not find the correct addres like lspci? This is a good
question. Maybe the kernel doesn't know what to search.
I have a somewhat fixed (not perfectly) DSDT/SSDT for A315-41G (Ryzen 5 +
Radeon vega 8/Radeon 535) which provides a better cpu power
No sorry, instead of pci=noacpi, try to start the kernel with noapic and
then check lspci. It there is a kernel panic by this way then use
pci=noacpi.

you (bountou), this is exactly the same problem what I have. Maybe there is a
little difference but not much. We will be able to fix it with a little work.
So this is an ACPI problem. ACPI(Advanced Configuration and Power Interface) is
a hardware interface what is afforded by the manufacturer
