After switching from kernel 3.2.12 to 3.3.8, I get NFS hangs when copying larger files (>10 MB) from another machine (NFS server) to this machine. When it happens, NFS is completely dead (df hangs, too).

I get this in the log of the client:
Code:
kernel: nfs: server <servername> not responding, still trying


dmesg | grep eth0 (kernel 3.2.12)
Code:
r8169 0000:05:00.0: eth0: link down
r8169 0000:05:00.0: eth0: link down
ADDRCONF(NETDEV_UP): eth0: link is not ready
r8169 0000:05:00.0: eth0: link up
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
eth0: no IPv6 routers present


dmesg | grep eth0 (kernel 3.3.8)
Code:
r8169 0000:05:00.0: eth0: RTL8168evl/8111evl at 0xf919c000, 00:25:22:bf:52:35, XID 0c900800 IRQ 42
r8169 0000:05:00.0: eth0: jumbo features [frames: 9200 bytes, tx checksumming: ko]
r8169 0000:05:00.0: eth0: link down
r8169 0000:05:00.0: eth0: link down

r8169 0000:05:00.0: eth0: link up
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready


ifconfig eth0 (both kernels)

Code:

        Kernel driver in use: r8169
        Kernel modules: r8169


I am loading the suggested firmware patch for this chip:
Code:
CONFIG_EXTRA_FIRMWARE="rtl_nic/rtl8168e-3.fw"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"



So, dmesg says "jumbo features" with 3.3.8, however I use MTU 1500.


Any help/hints would be greatly appreciated.

Does this still happen in newer kernels, such as 3.5?

I have not tried any unstable kernels, yet.

I can confirm, since I running >=3.3. I get the same trouble. If I use NFS more than normal (like big copy jobs), the connection freeze complete.

Logs are like this ("filer" is the hostname) :

Code:
Sep 16 16:15:01 [kernel] nfs: server filer not responding, still trying
Sep 16 16:16:08 [kernel] nfs: server filer OK
                - Last output repeated 82 times -


I can access the filerserver in this time (ssh/samba/...) and ping it. It's a LAN. There is no network trouble. Before it works fine. On other machines (with other/older kernel, like 3.0.x) I have not this problem (and I can accessing futhermore from this clients while my nfs connection freeze).

I guess there is really a problem.

Now I updated the server from kernel 3.1.10 to 3.5.7 and the issue is gone!

Seems that 3.1.10 as server and >3.2 as client has issues.
