I confirm the bug. I can reproduce it by copying a directory of 8.5 GB from a mounted NFS drive to a local drive on my Compaq Pressario V6850ED. Or by downloading the directory with FTP. Even by copying it from the mounted NFS drive to the same mounted NFS drive(!). I can do so from 2 different servers (one AMD-64, one Pentium4). I can do it with Kubuntu 8.04 AMD64 as installed on the V6850ED. Or by running Kubuntu 8.04 I386 live from the CD. I use different physical locations on our network with different UTP cables. I tried many combinations (not all of them) and the result is always the same: At 3% to 55% in the copy process the V6850ED freezes with a blinking capslock light.
However, if I replace the V6850E by a Compaq Pressario C760ED I can copy the same directory from the same mounted NFS drive without any problem. I tested this with Kubuntu 8.04 I386 as well as with Kubuntu 8.04 AMD64 installed. The C760ED seems a tropical machine that never freezes. The Compaq Pressario VG850ED has an AMD Turion 64 X2 TL60 processor @ 2GHz and 3072 MB DDR2 SDRAM. The Compaq Pressario C760 has an Intel Pentium T2370 dual core processor @ 1.73 GHz and 2048 MB DDR2 SDRAM. I hope this helps the Ubuntu team to resolve this problem. -- Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes. https://bugs.launchpad.net/bugs/147464 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
