I could collect two log files: dmesg and apport. 1. dmesg.txt I booted in recovery mode and then stored dmesg. System was hanging for 61 seconds by line 761: [ 2.454438] udevd[115]: starting version 175 And then an error message showed from line 769: [ 2.477182] [drm:drm_pci_agp_init] *ERROR* Cannot initialize the agpgart module. [ 2.478694] BUG: unable to handle kernel NULL pointer dereference at (null) ..... Continuing boot by logging out from recovery console fails, system hangs.
2. apport.txt I booted in recovery mode and ran: apport-bug linux --save ~/apport.txt Thanx, Roland -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1071699 Title: [Dell Lattitude E6420] Boot fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1071699/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
