Seeing something similar with kernel version 3.2.0-27-generic #43-Ubuntu Dell Inc. Vostro 470/0YJPT1
I get a general protection fault, not an oops, but the same __ticket_spin_lock appears. This has happened to me twice today. I installed Ubuntu 12.04 on this machine two days ago and haven't seen this previously. I found this via Bug #1017874. No USB devices were connected to the system since the last reboot, so my problem seems unrelated to USB. syslog excerpt attached. ** Attachment added: "syslog from lockup until I switched off the power" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/922906/+attachment/3238992/+files/syslog.20120727 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/922906 Title: Kernel Oops - BUG: unable to handle kernel NULL pointer dereference at 0000009c; EIP is at __ticket_spin_lock+0x8/0x30 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/922906/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
