Public bug reported: After an update/upgrade one of our Lenovo T 420s hangs with a system crash. I decided to re-install Kubuntu:
Using ISO CD with Kubuntu 12.04 64 bit 3.2.0-23 - Installatation succeeded and everything works fine. With no modifications to the plain system - other than supplying the WLAN credentials - I performed an apt- get update && apt-get upgrade. The upgrade didn't report an error and things appear to be ok and the systems aks for reboot. After the reboot the machine crashes with black screen and blinking cursor in upper left corner. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1171320 Title: Kubuntu 12.04 64bit installation crashes after update/upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1171320/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
