Hello,
I'm trying to get to work InfiniBand card (Mellanox) in Xen and DomU.
If I use SLAB_DEBUG I got the following message:
Slab corruption: start=ffff880098f513b8, len=256
Redzone: 0x1600000016/0x1700000017.

Unable to handle kernel paging request at 0000000398f5130b RIP:

Could anyone give me some hints how to track down the SLAB corruption?

have you already looked at Documentation/vm/slub.txt ?
