Through LFS 7.10 I've suppressed ACPI errors with a /etc/sysctl.conf
file containing 'kernel.printk = 4.'
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?
