Public bug reported: Hi,
when transferring around more than 1Go of data using the ethernet controller (04:00.0 Ethernet controller: Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet (rev c0)) with driver atl1c , my syslog gets full of messages "DMA: out of SW-IOMMU space for 4096 bytes at device 04:00.0" and my ethernet connection stops working. To reproduce this problem, I simply copy a few files from my internal SSD to my NAS. The byte size of the messages varies if I then try to access internet with my browser or any other network oriented application (smaller packets?)... sudo lspci -s 04:00.0 -vv 04:00.0 Ethernet controller: Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet (rev c0) Subsystem: ASUSTeK Computer Inc.
