are after netconsole has bailed out. Any obvious solutions I am missing?
The documentation is pretty clear on how to set this up, so there must
be some way to get it to work. I could find nothing on Google.
Here's the big clue:
Sep 24 22:01:25 dfpc60 systemd-modules-load[185]: Module 'netconsole' is builtin
which means that it's going to get initialized during *very* early boot, before
the initramfs gets called. netconsole is able to do the equivalent of
'ifconfig' (or at least enough of it to set the IPs/ports/ARP entries before
the rest of networking comes up), but it can't also get the physical device up and
running if the hardware driver isn't present.
Since it's builtin, this is probably a custom-built kernel. So make sure that
the driver for eth0 is also builtin.
Would you tell me how to tell the driver that it is to be eth0, ip
address etc. Maybe on linux command line, but I do not know the format.
Thanks
Don
