Hi there,
I hope I am posting to the right place. I have
been a user only and not a kernel developer.
I built myself a custom kernel with the kernel
config file attached at the end of this email.
It works. However, if I remove some of the
unused NICs (for example fxp, rl, sf), the kernel
complains that it cannot find device ad and
waiting with a 'mountroot>' prompt.
I built a kernel with DDB and boot the kernel
with -v.
Of course, I cannot really see the messages as
they scroll by rather quickly. In addition, all
the messages are not on disk, as the disk is not
mounting yet.
How can I proceed to find out why this is happening
and how to fix this problem? Thanks for your
help in advance.
