Thanks, will try those on 5.5.2.

What is crazy here?
Each one has a story.

Force?
Because then I can be certain it will be there, this has been there for
quite a while.
Or would you suggest I run my x86_64 without acpi? (I am not an expert
in this area yet)

noexec=on noexec32=on vga=0xF06 SYSFONT=latarcyrheb-sun16
LANG=en_US.UTF-8 KEYTABLE=us
fbcon=font:VGA8x16

Not important I guess.

acpi_enforce_resources=lax

To avoid conflict.

radeon.pcie_gen2=1

To enable PCIE gen 2

cgroup_disable=memory

No control groups for memory.

threadirqs

Theads for irqs.

plymouth.enable=0 rd.plymouth=0

No plymouth.

mce=dont_log_ce

To avoid logging.

panic=0

Kernel behaviour.

rd.lvm.vg=myvg  rd.lvm.vg=ssdvg

To have the kernel open the vg

radeon.dpm=1

We want power management

zswap.enabled=1

We want zswap.

rd.auto=1

enable autoassembly of special devices like cryptoLUKS, dmraid,
   mdraid or lvm.

audit=0

No audit.

systemd.log_level=warning

Less systemd clutter in logging.

ip=192.168.10.70::192.168.10.98:255.255.255.0:::off:192.168.10.98
rd.neednet=1

This is unnecessary.

net.ifnames=0

Old style network interface names.

amdgpu.gttsize=8192

Had to do with viewing larger PDFs, for genealogy etc.

clocksource=hpet

We want hpet. Not tsc.

amdgpu.lockup_timeout=0

rd.luks.options=discard

We want to use discard on our ssd's.

elevator=mq-deadline

We want a different scheduler for ssd versus hdd.

Kind regards,
Udo
