I believe that this is the same issue which prevents the EeePC from turning off when shutting down - caused by snd-hda-intel.
This is a widely documented problem with the EeePC, and a workaround is described in the Ubuntu Community Documentation: https://help.ubuntu.com/community/EeePC#head-59652af56e26236e0c4076af54096c7f0cc52d02 Although this problem is written about widely, it is strange that this bug has not been reported more widely on Launchpad. We really need a proper fix to be distributed to encourage the use of Ubuntu on the EeePC. ** Summary changed: - Gutsy hangs at shutdown + Ubuntu hangs at shutdown ** Description changed: PROBLEM: - Gutsy Gibbon hangs at shutdown and doesn't power off. + Ubuntu hangs at shutdown and doesn't power off. REMARKS: - At shutdown, the following message appears: NetworkManager: <WARN> nm_hal_deinit(): libhal shutdown failed - connection is closed - Some suspicious messages from dmesg: hda_codec: Unknown model for ALC880, trying auto-probe from BIOS... hda_codec: Cannot set up configuration from BIOS. Using 3-stack mode... apm: disabled - APM is not SMP safe. - To use the command "sudo rmmod -w snd_hda_intel" solves the problem and the computer power off. Furthermore, the network warning does not appear. To use the switch "-f" does not unload the module. - The system does not hibernate when using pidgin and, sometimes, firefox and it never suspends. CONCLUSION There is no conclusion since the source of the problem is not clear. It could be the sound driver, the network driver, the energy management or whatever else. This bug has been largely reported and confirmed (since 6.06), but never solved, I don't know why. ** Tags added: hardy -- Ubuntu hangs at shutdown https://bugs.launchpad.net/bugs/201813 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
