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
