This did *not* happen with 6.1-RELEASE and the msk driver on Marvell's website. >How-To-Repeat: Launch ktorrent and let it download for some time (usually less than 30 minutes, less than 10 if hw.pci.enable_msix and hw.pci.enable_msi are still enabled) >Fix: >Release-Note: >Audit-Trail: >Unformatted:
