disconnected host network on boot - removing vbox modules fixes the issue

[medigeek]

I am not sure if this is a duplicate, sorry if it is.

Problem:

Host (my physical machine) has disconnected network (ethernet) during boot sometimes. If I reboot the machine, the networking is fine.

Description:

• It seems random, does not happen always...
  

• I tried to remove and reload r8169, but didn't help. The problem seems to disappear once I rmmod vbox-related kernel modules.

Attached files:

• dmesg and several other "network debug" commands, showing the state of the network
  

• commands (modprobe -r) I used to remove vbox-related kernel modules and reload my ethernet kernel module (r8169)

Notes:

I have noticed that there is a new version (3.2.4-62467), I will see if it happens with that install as well.

Using VirtualBox 3.2.4:

$ apt-cache policy virtualbox-3.2
virtualbox-3.2:
  Installed: 3.2.4-62431~Ubuntu~lucid
  Candidate: 3.2.4-62431~Ubuntu~lucid
  Version table:
 *** 3.2.4-62431~Ubuntu~lucid 0
        100 /var/lib/dpkg/status

Perhaps the priority of 10-vboxdrv.rules is too high?

I believe that 70-* has a higher priority than 10-*. Since you are asking, did you try changing priorities and find that made a difference?

[medigeek]

very good suggestion.. :) As soon as it happens again (since it doesn't happen on every boot), I'll try it and let you know!

Can you try with 4.0.2 and confirm the problem still exists?

[medigeek]

Hi, I believe that the problem is resolved, thanks :)
