You should update your bios to v1.15
So there are no drawbacks with the new v1.15 bios?

I used windows to upgrade bios.
Didn't suspend work for you before?
I been using suspend and hibernate for a long time, well i almost
I have now upgraded to bios v1.15 and everything seems to work as expected and
i don't need to override IVRS anymore.
I couldn't replicate the slow boot loader, tried grub 2.04 and elilo and both
was working as fast as always.
This bug is finally fixed in bios update.

Do you use any other options or overrides?
cat /proc/cmdline
What kernel works for you with only acpi_osi="Linux"?
What does your dmesg look like?
I have previously tried
Yes i got bios 1.13.
The bug with being forced to add my grub as trusted file was in earlier bios

@Vladislav Kamenev i still need ivrs to boot 5.1-rc5 kernel.
Since there was talks about problems with hibernation i even setup a swap file
and tested hibernation (Suspend to Disk S4) and it works, i normally only use
suspend (Suspend to RAM S3), suspend works with all my kernels 4.19+ and ivrs.
I have IOMMU and SVM enabled in bios/UEFI.
I toggled Secure boot setting and it doesn't change anything, hibernation works
anyway and i still need ivrs to boot.
I tried with secure boot enabled and hibernation works with all my kernels
(4.19.34, 5.0.7, 5.1-rc5).
Since i use a swap file for
I just tested battery time in windows, with full brightness as i had in
previous tests and i was able to get about 15 extra minutes from windows 10, my
guess is that's because windows forced a power save mode when there was under
20% left of the battery charge.
There was no compilation in
Maybe it worked with kernel 4.19 with your distribution but touchpad didn't
work for me since i only use vanilla kernels without patches.
Ubuntu patches i2c-amd-mp2 support, in older kernel series there was an older
version that didn't work for many laptop users that needed to recompile the
As i wrote i still use parameters.
ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2
For me i couldn't boot with anything other then pci=noacpi before, but now ivrs
parameters work and i got a working touchpad.
"Things seem to work" is because i have only used the laptop for a day and i
haven't
I forgot to add that some distributions may include i2c-amd-mp2 built in to the
kernel and that may be an older non working version.
If that's the case then you need to rebuild the kernel without the patched
i2c-amd-mp2 support and then you can add i2c-amd-mp2 as i posted in previous
post.
I
With bios/UEFI 1.13 and kernel 5.0.7 things seems to work.
I got touchpad working by installing https://github.com/Syniurge/i2c-amd-mp2
(master works, the wip-v16 doesn't work and screwed up a lot of things when i
tried it so don't try that version).
git clone
@Darksurf i looked at that laptop model and there was an 1.12 bios for it but
the changes wasn't that exciting.
Bios 1.12
"1.Add SCCM solution.
2.Change touch pad mode from basic to advance for linux sku."
I do know that A315-41 got the touchpad changes as well with 1.13
