Hi, Always look at the chipset on these HP/Dell/IBM cards. They're always a standard Broadcom, Intel or Mellanox (Nvidia) chipset underneath with Dell or HP only relabelling the card. This 331T is a Broadcom BCM5719, so that's what you want to investigate. Often these pcie cards, or the host system, do not fully support PCIe active state power management. If you have a BIOS option to disable that try experimenting. Otherwise the kernel option "pcie_aspm=off" may help.
