Yes. You are right. It is a vendor kernel based on 2.6.9 along
with some vendor specific kernel patches.
I agree that it is not always possible to support older kernels
and i was not expecting you to do that.
I tried to do this myself by identifying the tso related patches
that went in after 2.6.9 and just wanted to find out if i missed
any other patches that may have fixed the tso related assertions.

We will try to see if this problem can be reproduced with
2.6.10-rc2.

Thanks
