Bug ID: 196650
Summary: [PATCH] Display progress during getmemsize() so the
kernel doesn't look like it hanged
Product: Base System
Version: 11.0-CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern

Add a progress indicator to getmemsize() memory mapping - print a dot every GB
Several people have noticed that there can be a long, silent pause early in
boot on amd64 systems with large amounts of physical RAM. This is while all the
memory ranges are getting mapped in. Even with the memory tests disabled, this
can take a noticeably long time, to the point that its easy to think that the
kernel has stopped booting. The attached patch provides a basic progress
indicator (print a dot as every GB is mapped), so it is obvious that progress
actually is being made.
