Subjectbad pages when up/down network cable
Message-ID<pM3UT-8kr-41@gated-at.bofh.it>
1、the host directly link to the storage device，by intel ixgbe NIC;
between them, no switch or router.
2、the nic of the storage device suddenly become unused and then OK 
after a little time, this happened frequency.
3、the host printk a lot of message like these:

The kernel is SUSE 3.0.13, use slab, and the following log shows the 
page still have PG_slab when free_pages(). Does anyone have seen the 
problem?
