I firstly discovered this on 2.6.22-6~bpo40+1 (debian's backports), but I'm not sure if that was same thing (it is long ago). Now i tested on test machine with these kernels: 2.6.24, 2.6.24.6 (http://ya.bofh.cz/archive/kernel-2.6-htbcrash/2/netconsole-2.6.24.6-slon.txt), 2.6.25 I can test anything you want. > Very nice description and logs, but alas I'm not able to test it, so > a few questions: > > - there are quite a lot of networking modules loaded like bonding or > ifb: are there some other scripts (especially with virtual devices)? I kicked them out now (ifb, vlan, bonding).

Yes.
