I have a mellanox card plugged in numa node 6.The CPU is AMD with 8 NUMA nodes
I have these messages popping up[387380.177067] 0000:c1:00.1: IOMMU mapping error in map_sg (io-pages: 2097152)
This goes on for 15-20 min and after that it vanishes and my application comes up
I tried debugging it but didn't find anything substantial
Any idea why ?
