We currently have three machines at work that show this behaviour: On shutdown, the system will hang with output resembling what the original poster described in his bug report (Netmanager lines etc.). Every now and then, this output is followed by "Sending all processes the KILL signal", but none of the machines will shut down any further. This is the single-biggest showstopper that prevents us from rolling out (K)ubuntu at the moment. What I have been able to gather so far is this:
Machine 1: An Acer TM8104WLMib Laptop with Kubuntu 7.10 i386 installed from the alternate disk, with all updates. I tried adding "acpi=off" to the boot options, but that results in the network interfaces not being recognised and didn't seem to help anyway. This machine *will* shut down if I choose "console login" (hence shutting down X first) and the issue "shutdown -h now" from the command line. Machine 2: Desktop with Asus P5L-1394 motherboard and an Intel PD925. Kubuntu 8.04 i386 without any updates, installed automatically via preseeded network-install, using the alternate CD as starting point, but with a complete mirror (via apt-mirror) of "dists" and "pool". Originally, this machine had Kubuntu 7.10 and needed to be installed using a second NIC, as the onboard NIC (Attansic L1) was not recognised by the install kernel. In that case, the shutdown problem vanished when I removed the second NIC. It returned, however, when I installed 8.04 using the onboard NIC only (fortunately, 8.04's install kernel *does* support the chipset). Machine 3: Desktop with Asus M2A-VM motherboard and an AMD Athlon X2. Kubuntu 8.04 i386 installed automatically via preseeded network-install, using the alternate CD as starting point, but with a complete mirror (via apt-mirror) of "dists" and "pool" (like machine 2). All updates including the latest "proposed" ones are installed (to check what was said by Adolfo above). Still having the shutdown problem. I tried adding "irqpoll apci=off" to the boot options, but that did not change anything. Again, if I choose "console login" and press Ctrl-Alt-Delete, the machine will shut down properly, though not power off. Using "normal" shutdown it hangs in the manner described above. I have also tried to boot this machine with the Kubuntu 8.04 i386 Desktop Live CD and in that case, the machine *will* shut down properly (after having displayed the "Remove CD" message) -- system hangs at shutdown https://bugs.launchpad.net/bugs/138691 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
