It looks like your system hung up while trying to do a PCI Config read of Capabilities 0xd0: VPD (Vital Product Data). I have a 9240 controller, and with kernel 3.5.0-rc1, I can do lspci -vvv : Capabilities: [d0] Vital Product Data Unknown small resource type 00, will not decode more.

I would also try upgrading your controller firmware. -Adam -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
