David, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .
If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux <replace-with-bug-number> Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it. Please let us know your results. Thanks in advance.

Both are connected via Gigabit Ethernet. 4) I'm facing complete system lock-ups at the client machine (only reset button helps) when receiving large amounts of data from the NSF server. The server itself doen't seem to be affected by this problem. I did the following tests: - Copy files of various sizes (up to 2 GiB) from the client to the server -> WORKS - Copy small files (like 100 MiB) from the server to the client -> WORKS - Copy bigger files (like 1 GiB or more) from the server to the client -> CLIENT LOCKS UP (I'm actually able to copy a 1 GiB file which I copied from client to server right back from server to client afterwards successfuly. But since this doesn't seem to cause any network traffic I'm assuming this is just 'fake' and in reality the file is copied back from some cache at the client. Having a 2 GiB file this situation also causes a lock-up.) Other situations that caused Lock-Ups: - Letting the Strigi Indexer oft the client index files on the server's NFS share - Extracting archives via the client which are on the server's NFS hare - Watching on the client a movie which is on the server's NFS share (but here it does only seldomly lock-up. Movies with low bitrates didn't cause any problems yet while movies with high bitrates only sometimes and after various amounts of time are causing problems) It doesn't matter if I copy the files using 'cp' or some graphical file manager by the way. - - Having those observation results it seems that the NFS client causes the system to lock up when receiving big amounts of data. - + Having those observation results it seems that the NFS client causes the + system to lock up when receiving big amounts of data. According to /proc/mounts my NFS shares are mounted as follows: 192.168.1.101:/media/data5 /media/data5 nfs rw,sync,nosuid,nodev,noexec,noatime,nodiratime,vers=3,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.1.101,mountvers=3,mountport=53457,mountproto=tcp,addr=192.168.1.101 0 0 The Kubuntu 8.04 Client I had before on which those problems did not occur had quite similar setting, I believe.
