Rough edges and how I work around them (or not)
ClassicHasClass:
Are you on Fedora? fstrim.timer will become default in F32 (hopefully).

For the longest time, I was under the impression that my distro enables trim by default. Checking systemctl reveals that it is not even running. Looks like I have a project to do!

There is a bug in SSD trimming (discard) with NVMe SSDs in the kernel until version 5.4:
[FIXED in stable kernels 4.19 and 5.4] https://bugzilla.kernel.org/show_bug.cgi?id=202665 IOMMU related errors when performing discard on some NVMe devices (mainly NVMe SSDs). Current workaround is booting with the kernel parameter "'iommu=soft'', see the https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=530436c45ef2e446c12538a400e465929a0b3ade patch
I am currently using Fedora Server 31 with Kernel 5.4.13-201.fc31.ppc64le and cannot observe NVMe problems or crashes anymore like with Ubuntu Server 19.10 and Kernel 5.1.x (but I have to do more tests for that).
ClassicHasClass:
For certain devices. This machine is fine with a 5.3 kernel (haven't got around to updating it yet), and the Samsung NVMe SSDs Raptor ships appear to be unaffected.

ffmpeg botches gif creation when using palattes - standard (ugly) gif creation with ffmpeg is fine however
same exact config + script works okay on x86

Can you please see if this is fixed by this update?
Please confirm the ffmpeg version you are using

I will tag this to check. I am currently on ffmpeg 4.1.6.
