While running stress2 using trevorjk's vkernel setup with the

fixes for the vkernel) I got a mbuf panic:
Hoho, I tried to reproduce it in real kernel but failed in the last two days :P
I will try vkernel today.

Hi,
Was this running a particular test or running all the tests?

Hi,
I haven't been able to reproduce it (with the test I've tried)
Feel free to reopen it (or open a new one) if you think the issue is still there.
Cheers,
Antonio Huete
