This means that the second and subsequent boots for an LTSP client fail because the sourceip / sourceport pair on the nbd server is still occupied by the old nbd connection. The patch net: avoid dependency of net_get_random_once on nop patching https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3d4405226d27b3a215e4d03cfa51f536244e5de7 should fix the issue and also went into -stable: http://www.spinics.net/lists/netdev/msg282397.html https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=adeb3fe4ef6621793d7f1d6f0b9c9cc88827c5b7 ) There are three independent reports on ltsp-discuss for this issue and the original analysis was posted here: https://www.mail-archive.com/ltsp-discuss@lists.sourceforge.net/msg41764.html The issue can NOT be reproduced in VirtualBox and may be limited to certain hardware - other users report they see no problems with 3.13. However, as this is a -stable patch it should be applied anyway.
