Does this mean the bug triggers in 2.6.25 and later, but not in 2.6.24?
If so, is it possible to reproduce this e.g. with 2.6.25-rc6?

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)?
- could you send vlan and routing rules on this router?
- does it always break with the same traces?

Thanks,
