Through LFS 7.10 I've suppressed ACPI errors with a /etc/sysctl.conf file

However, with LFS 8.0 and the 4.9.9 kernel the errors aren't suppressed.
Is this a kernel issue? I see the following in Kernal Hacking/printk and
dmesg options --->:
Default message log level (1-7) (NEW)
The default value is 4. It seems that should make /etc/sysctl.conf
unnecessary. But building the kernel with that value displays
never-ending ACPI errors, with or without /etc/sysctl.conf. This isn't a
significant problem as it occurs only in command line mode but it is
annoying.
If I boot my 8.0 build with the 7.10 kernel and /etc/sysctl.conf the ACPI
errors are suppressed. That suggests there's not an error with my 8.0
build. Logical?
You don't say if you are building sysv or systemd. If sysv, edit
/etc/sysconfig/rc.site and change the line:
#LOGLEVEL=7
to
LOGLEVEL=4
The actual command is in /etc/init.d/rc
dmesg -n "${LOGLEVEL:-7}"
If you prefer, you can also set LOGLEVEL in /etc/sysconfig/console.
