Subject: list debugging BUG() hit by aic94xx

Message-ID: <1159901803.3443.47.camel@mulgrave.il.steeleye.com> (raw)

If someone is bored, they can take a look at this list debug error:

list_add corruption. prev->next should be dfa0b788, but was f795fd50

This seems to be coming from the

	list_add_tail(&dev->dev_list_node, &port->dev_list);

in sas_get_port_device()
