This issue effects all Intel Core i5 Thinkpads. This happens on the T410 & X210 I have here. There is a kernel oops after the first suspend, this is ultimately leading to the reboot.
The issue is worst as after the oops the usb ports are also unusable after the first suspend. So the kernel oops put the machine in a bad state. dmesg from X201 is attached. It looks as though pm suspend looks to be triggering the issue. ** Attachment added: "dmesg_x201_after_1st_suspend" http://launchpadlibrarian.net/41679975/dmesg_x201_after_1st_suspend -- [Lenovo 2537AD3, 2537AB8] one successful suspend/resume per boot https://bugs.launchpad.net/bugs/532374 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
