I've removed the bonding, changed to use eth0 directly, booted it with destop kernel... No problems with ping so far, but it were unable to stop the network: a ip link set down br5000 were in D state and ip a s on another still open console stopped as well in D state... ?! kernel-desktop: with bond: no packet drops, ip link set dev br5000 down -> D / blocks shutdown without bond: no packet drops, ip link set dev br5000 down -> D / blocks shutdown kernel-default: with bond: no packet drops, no (shut)down problems without bond: no packet drops, no (shut)down problems kernel-xen: with bond: no packet drops, no (shut)down problems without bond: no packet drops, no (shut)down problems -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It is not limitted to vlan + bridge -- the network & later system freeze may happen while another operations as well, as soon as a vlan interface is in use.

Seems to be solved in latest kernel:

Ah... You were testing with a 'default' kernel, not with 'desktop'. With 'default' kernel I'm getting packet drops (bnc#678540) but no freeze. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
