Tested "latest upstream kernel": the mainline kernel does NOT fix the bug. Tag 'kernel-bug-exists-upstream' added, bug marked as 'Confirmed'.
More verbose blurb below.

It did not respond to any keyboard or mouse input (including no response to alt-ctrl-delete, alt-ctrl-backspace or alt-ctrl-F1). Even the power button was un-responsive, had to hold it for 10 seconds to turn off power (whereas the previous time I got the machine to freeze it responded to a quick press of the power button and it shut down (cleanly?)). ** Tags removed: apport-collected precise ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1098961 Title: PAE regression: OOM with just a few sleeps To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1098961/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
