So far I can *not* reproduce the problem with 3.0.17 (transfered 8gb of data). However, with 3.0.32 I can reproduce every time by copying a 20mb+ file. If you want, I can test a few kernels in between .17 and .32, but that's going to take some time. FYI: I do notice short hickups on the client, but those are most likely just because the disks aren't fast enough to handle the write requests. I'm running with Gbit ethernet and reading is obviously faster than writing and writing is slower than the link limit, resulting in the network buffers filling up. I don't consider this a bug. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
