I am having a very similar problem. Random freezing, but it does seem to be caused by high amounts of network traffic. For example, I can consistently freeze my machine when I do an rsync backup of a large directory (as in 50GB or so) over my LAN to a server machine.
I am *pretty* sure that I did not have this problem until a relatively recent update. I disabled my wireless in NetworkManager (right-click->Disable Wireless) and am using the wired network and this problem went away! I mention it like this because I do see the wireless card on the system still (i.e. in lspci) and the wireless modules are still loaded, AFAICT. (i.e. I did not disable wireless in the BIOS) System stats: Lenove R61 Ubuntu 8.04 uname -a: Linux jeff-laptop 2.6.24-21-generic #1 SMP Tue Oct 21 23:43:45 UTC 2008 i686 GNU/Linux See lspci -vvnn output, attached. ** Attachment added: "Output of lspci -vvnn" http://launchpadlibrarian.net/19738262/lspci.out -- Madwifi (atheros) driver malfunction induces a system freeze https://bugs.launchpad.net/bugs/276445 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
