The issue is that I was attempting to upgrade from 4.7.4 up to 4.8.6. Nothing was changed. When I did try to boot the new kernel I got a file system error message related to ext4. This also created a corruption in my /dev/sda3 file system (ext3) and I had to manually correct it (that might have been due to unclean unmount since I had to cold reboot the computer). I did test to switch the setting from compiled in into modules, but that did not solve this issue. The ext3 file systems mount properly it seems, regardless of the errors I got later on after cold reboots on the computer. I did not get into the shell following this issue. I don't think this is any type of misconfiguration at my end. Since I follow rather regular and stable setting if possible. sdb1 is a ext4 file system. While the rest is ext3. I don't have any issue with kernel 4.7.4 with the same setting. The size is 1TB. I get this in my rc.log. I'm running Gentoo linux and compiling the kernel with genkernel (for convince). ---- * Setting system clock using the hardware clock [Local Time] ...
