I have a test server running 4.3-STABLE (cvsup last run sometime last
week). Whenever I boot with my custom kernel I get almost the same
messages as Sergey, but when I boot a GENERIC kernel compiled from the
same sourcetree the test server boots as expected and mounts the root
file system.
I haven't tried the boot0cfg command Sergey suggest, but I don't see
the relevance. Can someone please enlighten me if I'm wrong.
All I did when configuring the custom kernel was to comment out the
inclusion of various stuff this test server does not possess, such as
the EISA bus, network interface cards, SCSI controllers, USB devices,
etc.
I have tried all things, commenting out the old ata driver (ata0 and
ata1), leaving the new stuff, and vice versa. I ended up using the
GENERIC file and just adding my custom options such as KERNFS and
setting the number of pty's to 256.
This are the relevant parts of the dmesg from the custom kernel
(written down on paper and typed in later):
...

Here's the dmesg from the GENERIC kernel I compiled myself and the
one the test server is currently using:
