On my T60 3.2.0-33-generic-pae it seems very likely to be related to the docking station (or to a pair of them). This is on BIOS 2.27 25 Apr 2011.
After suspending while docked in station A, it hung on resume in station B. This did work fine before. It continued to hang on boot even after hard reboot, undocking, and full battery removal (a couple of tries). I checked the log only on last hang: "Illegal UART type: undefined". It booted successfully only when I re-docked and booted while docked (using power button on dock -- that might make a difference). I successfully suspended while docked and resumed fine previously (on this BIOS version; old BIOS would lock up in this scenario). Once the boot failure happens, it's persistent, but it does not seem reproducible at will. If I do reproduce it, will try to test upstream. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1070994 Title: Boot failes after upgrading the kernel from 3.2.0-29 to 3.2.0-30 and following To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1070994/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
