Subject: Re: panic 2.6.27-rc3-git2, qdisc_dequeue_head

All patches applied.
On normal shaper i got just this warning mentioned before.
On alternative shaper (it is not using TBF anymore, it is using flow 
classifier and many HTB classes) - it is panicing. 

After applying all rules, most probably it is happened when some traffic 
passed over there. I can't be absolutely sure in that, but it looks like at 
that time there is no actions by iproute2/tc done. Just traffic.

This is same PC where WARNING appeared which i mention in previous mail. So 
maybe it is result of that warning, no idea... 

Here is latest panic (alternative shaper):
