0007051: kernel crash (hard lockup) with high traffic and HTB shaping enabled

Hi,<br /> <br /> we are seeing reproducible kernel panics on a web server with ~4Gbit outbound traffic (200k pps in, 400k pps out) with traffic shaping enable. The problem is reproducible and happens in ~minutes aftere enabling the shaping.<br /> <br /> If we disable the shaping, the machine works fine.<br /> <br /> Please find attached several kernel traces when this occurs.
