I am trying to use netconsole to examine some problems I am having
booting Alienware 13 r3 and 14 laptops. I am running opensuse 42.3 with
generic 4.18.7 kernel configured to include netconsole. After building
my kernel and including the proper command (as shown below) in the linux
boot string:
netconsole=64001@192.168.7.60/eth0,64001@192.168.7.55/34:e6:d7:01:2a:dd
I receive the following error message, as shown by journalctl:
sudo journalctl -b | grep netconsole
Sep 24 22:01:25 dfpc60 kernel: netpoll: netconsole: local port 64001
Sep 24 22:01:25 dfpc60 kernel: netpoll: netconsole: local IPv4 address
192.168.7.60
Sep 24 22:01:25 dfpc60 kernel: netpoll: netconsole: interface 'eth0'
Sep 24 22:01:25 dfpc60 kernel: netpoll: netconsole: remote port 64001
Sep 24 22:01:25 dfpc60 kernel: netpoll: netconsole: remote IPv4 address
192.168.7.55
Sep 24 22:01:25 dfpc60 kernel: netpoll: netconsole: remote ethernet
address 34:e6:d7:01:2a:dd
Sep 24 22:01:25 dfpc60 kernel: netpoll: netconsole: eth0 doesn't exist,
aborting
Sep 24 22:01:25 dfpc60 kernel: netconsole: cleaning up
Sep 24 22:01:25 dfpc60 systemd-modules-load[185]: Module 'netconsole' is
builtin
I examined the timing in more detail and found that the above "eth0:
doesn't exist" message comes at Sep 24 22:01:25.080603.
The wicked message eth0: up comes at Sep 24 22:02:01.173616. The
difference is maybe 36 seconds? There is an eth0: avail message at Sep
24 22:01:34.112744, don't know if that would suffice for netconsole Both
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.
This is my first post to this list, so if this question is not
appropriate please let me know without flames:-)
