Hi, I have the same problem with data corruption (with nfe on nfs server side), particularly when transferring large files. Maybe this is somehow associated with the topic. My simple test case: truncate -s 1000m bigfile ^^ here I get zero-filed file cp bigfile /nfs/mounted ^^ here I get not-at-all-zero-filed file, after uploading to nfs server I looked at the corrupted file. It contains a few ranges, filed with non-zero bytes: equal to zero? real 4-byte value offset ====================================== not equal 1200355616 at pos=38797316 ... <-- this range contains per-4bytes garbage, omit not equal 3879749905 at pos=38813696 not equal 161160732 at pos=45613060 ... <-- ditto not equal 575257183 at pos=45629440 not equal 1943682165 at pos=59768836 ... <-- ditto not equal 2843639625 at pos=59785216 not equal 2653910121 at pos=60293124 ... <-- ditto not equal 3462830780 at pos=60309504 Some info: nfs server on 8-CURRENT as of Apr 17 nfs client on 7.0-STABLE as of Apr 12 dmesg | grep nfe nfe0: <NVIDIA nForce2 MCP2 Networking Adapter> port 0xe000-0xe007 mem 0xe2001000-0xe2001fff irq 20 at device 4.0 on pci0 miibus0: <MII bus> on nfe0 nfe0: Ethernet address: 00:04:61:6c:76:b1 nfe0: [FILTER] nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 nfe0: tx v1 error 0x6001 ^^^ This appears while cp'ing file to server.
