The kernels I built did not work properly. One machine just hung with a flashing cursor. The other booted and ran and actually performed quite well however it would not respond to a USB keyboard and mouse so I suspect I removed some necessary hardware support.
Not this week but in time I am going to build some kernels with the same configuration as the existing kernels with all the added stuff defaulted so I can determine if it’s an issue with that version of kernel or a configuration item.
The kernels are identical configurations on almost identical hardware. Nothing logged gives me a clue. On the machine that hung there are no error messages.
