kernel: DMA: Out of SW-IOMMU space for xx bytes at device xxxx
Issue
- I have two Dell R710 servers that I have Red Hat 5.6 x86_64 installed on.
- The issue I'm having is that I am attempting to copy a large amount of files from server1 to server2 using:
scp -rp file server2:/root/
- On occasion, I notice that the transfer will drop to stalled state after about 10 seconds and when I check the console of server #2, it has kernel panic'd.
