Ryzen does indeed implement the x86-64 ISA, but it introduced a few changes which matter for a kernel such as Linux.
Ryzen 5000 is part of Ryzen Gen 3, which uses a new “family” identifier, 19h (the previous Ryzen generation was family 17h). Many of the patches involve adding support for this, even if that only involves telling the kernel that family 19h ...
When troubleshooting early boot issues on VMware, it might be useful to configure the kernel to use a serial port as a console. You'll need the kernel boot options for that: in your case, the only ways to specify them might be via the CONFIG_CMDLINE kernel configuration option, or with the FDARGS="..." environment variable during the kernel build, ...
Your tail command also gets its input from the page cache. The whole point of the page cache is that a process (any process, not only the process writing to the file) can find the wanted data quickly from the cache, without accessing the disk.
The pdflush kernel threads have been replaced by per-backing-device kernel threads. This LWN.net article describes ...

You could change log level with proc file:

The C library relies on the kernel for many of its functions; if the kernel were to try to use the C library, you’d end up with a loop. The standard C headers are provided by the C library and can’t be used either. The only libraries which could be used in a kernel are libraries with no external dependencies of their own, including to the C library (which ...

See man cgroups:
In cgroups v1, a distinction is drawn between processes and
tasks. In this view, a process can consist of multiple tasks
(more commonly called threads, from a user-space perspective, and
called such in the remainder of this man page). In cgroups v1,
it is possible to independently manipulate the cgroup memberships
of the threads in a ...
