I have the same issue with Kubuntu 10.04 beta and kernel 2.6.32-20/2.6.32-21 on Sony VAIO VPC EB1E1E.
For me the crash occurs right after I choose Reboot or Shut down from KDE Application launcher menu. It shows that plazma-desktop crashed with Segmentation fault and after few seconds reboots/shuts down. Workaround: If I reboot/shutdown by running 'sudo reboot' / 'sudo halt' it doesn't crash. The reason I didn't reported this myself is because apport failed with "Permission denied" every time I tried to generate the crash report. -- WARNING: at /build/buildd/linux-2.6.32/kernel/softirq.c:143 local_bh_enable_ip 0x7b/0xa0() https://bugs.launchpad.net/bugs/565425 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
