I have to confirm this problem. Same Hardware (Asus a6tc). The problem only exists when using X. It is not related to the ubuntu kernel, but exists also for non ubuntu kernels including 2.6.21. It seems that the NIC-module (R8169) crashes. Due to IRQ-sharing of NIC and graphics adaptor the whole system does not respond when NIC crashes.
Is there any way to assign a different IRQ to the NIC without disabling ACPI? Unbelivable anoying bug! I would be very gratefull if anybody could solve it, as this bug makes the computer nearly unusable in a networking environment. I guess that the following solution-approaches should be examined: 1. Let kernel assign different IRQ (I have no idea if this is possible, as ACPI assigns IRQs - maybe there is someone who is more experienced with this certain topic) 2. Check whether NIC-module crashes or graphics adaptor crashes 3. Repair guilty module (again I'm not enough familiar with linux kernel-modules hacking to do it myself) 4. I'm not sure whether this problem is related to usage of Nvidia proprietary graphics driver - should be checked I would love to help by testing and reporting. Just ask, but somebody please take this bug serious. ** Attachment added: "Output of dmesg" http://launchpadlibrarian.net/8483187/dmesg -- RTL8111/8168B hangs whole PC (r8169) in feisty https://bugs.launchpad.net/bugs/91895 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
