I just built a new PC, and I'm having a problem getting it to boot with
a custom configured kernel (gentoo-sources-5.2.4.) If I start with a
blank config and work through "make xconfig" the resulting kernel and
initramfs (genkernel) doesn't boot (just hangs after loading
initramfs.) So, starting with the config from the running kernel from
the live install medium, running make oldconfig then genkernel, it
boots fine. I assume my problem is removing something important while
trying to remove all the unnecessary options for supporting hardware
I'll never use.
However, if I start with the .config which workd, and "make xconfig"
and select "Supported processor types" under "Processor type and
features" and then unselect "Support Intel Pprocessors" (I have a
Ryzen) and save the config, it decreases the size of .config from 169K
to under 13K, losing almost every setting in the file.
Even stranger, if I look at "Local version - append to kernel release:"
it still shows the value I had previously set - but that setting
CONFIG_LOCALVERSION is NOT in .config. If I close the tool and start
it again, that setting is now missing and it looks like all settings
have been reset to the clean starting defaults (i.e., many say "(NEW)"
Am I missing something here, or might this really be a bug in "make
xconfig" ?
Can anyone else replicate this? While I don't think it's related to my
problem getting a non-booting kernel, it certainly has me confused.
Thanks for helping me confirm what's left of my sanity.
