Hi Nikola,
Seems like the link below is the same file you shared before - I don't see any errors there.

Two things you can collect for me to help debug this issue:

1.
Output of ethtool -d eth1 after problem occurs (redirect to a file)

2.
dmesg after enabling link related debug messages. Use
modprobe bnx2x debug=0x4
Or
ethtool -s eth1 msglvl 0x4
to enable these prints.

This holds for both of your problems (unless it is the same issue).

Thanks,
Ariel
