After I had installed the new bios from Acer support site the kernel loaded
with and even without ivrs kernel parameters however the GUI didn't start if I
used the ivrs parameters.
Could somebody confirm this?
So the new bios cuold be a fix for this issue.

Hi Suravee Suthikulpanit,
Thank you for the reply.
noapic is not needed, that had been just a worse option before we found out the
ivrs option.
So you say this can not be fixed in kernel permanently. I would be happy
if no kernel parameter was needed. Many people don't know about this,
Or in this cases why does the kernel not find the pci "devices" somehow
like we do?

For the grub lagging, try this:
sudo nano /etc/default/grub
GRUB_GFXMODE=1280x800
sudo update-grub
If this doesn't fix it you can try another resolutions.

Dear kernel developers,
the ACPI seems to be OK from kernel v 5.1 but only with using the ivrs_ioapic
kernel parameters. This is almos a constant failure by these notebooks.
Couldn't this be hardcoded somehow into the kernel?
This bug is almost one year old and we know how it can be fixed but

That is not clear if their bios should meet the standards or not. It's
also not clear if we should accept that they support Win10 only. I don't
really know.
Maybe this is something which is relate to this. What do you think?
Kung Lao, the market share of Linux desktop is very low so supporting it
hasn't got high priority, unfortunately. However the manufacturers
should be more flexible because of the future opportunities.

Both way worth a try. You could be right about Linpus, we should figure

Zhang Rui,
why have you changed the topic? It was correct, the kernel loads only
with noapic or noacpi. The problem is DSDT/SSDT tables can not load

Hi, I was trying another kernel parameters and noapic seems to work. It is not
needed to disable the whole ACPI "service", however I don't know how important
apic is. On kernel 4.18 even temperature sensors appear.
Power management is almost perfect if cpu governor is set to powersave.
