Despite the numerous boots I was still unable to reproduce the initial printk+0x2d\/0x2f, so it may be fixed in Main or masked by the print_bad_pte+0x187\/0x1e0 (though this still is based only on two datapoints in a frustratingly random issue).<\/p>\n<p>Whether RC6 is enabled or disabled doesn&#8217;t seem to have bearing on this. 3.2.0-17 produces printk+0x2d\/0x2f either way [3], and 3.2.0-18.28 also panics, though less consistently: I was only able to produce a sure printk+0x2d\/0x2f once [4], with 3.2.0-18.28 non-pae. Mostly the errors fail to reveal themselves, and when they do, they are different from printk+0x2d\/0x2f but also from each other: a couple of times a warn_slowpath_common+0x72\/0xa0 (as in\u00a0<a href=\"https:\/\/bugs.launchpad.net\/bugs\/917668\">Bug #917668<\/a>, though the hardware and pointers are different) occurred [5], and once it was a Bad page map [6] in unity-greeter.<\/p>\n<p>* [1]\u00a0<a href=\"https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/32\" rel=\"nofollow\">https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/32<\/a><br \/>\n* [2]\u00a0<a href=\"https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/29\" rel=\"nofollow\">https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/29<\/a><br \/>\n* [3]\u00a0<a href=\"https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/33\" rel=\"nofollow\">https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/33<\/a><br \/>\n* [4]\u00a0<a href=\"https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/34\" rel=\"nofollow\">https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/34<\/a><br \/>\n* [5]\u00a0<a href=\"https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/35\" rel=\"nofollow\">https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/35<\/a><br \/>\n* [6]\u00a0<a href=\"https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/36\" rel=\"nofollow\">https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/926007\/comments\/36<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In 3.3.0-030300rc4, printk+0x2d\/0x2f is either fixed or masked by print_bad_pte+0x187\/0x1e0.
