With persistent booting I was able to get a panic [1] showing with 3.3.0-030300rc4, and it looks the same as what the dmesg I posted in #29 [2] showed: print_bad_pte+0x187/0x1e0 is on top the Trace. 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).
Whether RC6 is enabled or disabled doesn’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 Bug #917668, though the hardware and pointers are different) occurred [5], and once it was a Bad page map [6] in unity-greeter.

I’ll upload a bunch of new screenshots for reference. They’re all related to testing this so bear with me, I’ll explain them further after uploading.
Still present in upstream 3.3.0-030300rc4 as it was in 3.2.0-17.27.
I tested 3.3.0-030300rc4 and couldn’t verify that the panic that all the 3.2’s above have is still present. Unfortunately I couldn’t prove it doesn’t either: with -intel, the first boot resulted in the ’low graphics mode’ failsafe dialog with Traces in dmesg (I’m attaching it). All subsequent boots resulted in panics that didn’t reveal a Trace, so they may or may not have been the one at hand. The panics still occurred when LDM should’ve launched, visually it either just showed the last lines of boot log or that with the mouse cursor. (The what’s-that-key was also blinking on the keyboard.)
Oho hei Syksyinen! Kaappaanpa härskisti tämän langan, ja kysyn, että oletko vaihtanut tyylilajia, vai onko joku napannut vanhan blogiosoitteesi uusiokäyttöön?
I’ve been waiting for an i386 build of RC5 to appear in the directory but it hasn’t. Should I try RC4 instead or keep waiting until a newer i386 build appears? AMD64 isn’t supported by the processor.
Unfortunately I didn’t make a note of when exactly the issue began. But I can give you a timeframe: it wasn’t there when I filed Bug #903831 on 2011-12-13, probably still not there on 2011-12-16 when I made comment #5 on the bug, and probably was there when I made comment #7 on that bug on 2012-01-06. (I’m being cautious with the ’probablies’ because of all the overlapping issues here.)
Again, thanks for the effort you put into your answers. After leaving the previous comments I felt slightly worried whether I’m too eager to dish out my kitchen psychology. These are deeply personal issues for you and for me to label you as this or that based on the little I (really) know about you is just my typical self-centeredness: I tend to get too fascinated with my own mental constructs to take into account that people I involve in them might not be as enthusiastic about them.
(Thanks for the video link btw, haven’t had time to properly watch it yet but I will.)
Yeah, AP’s a tough read to say the least. :) Still, I’ve plowed through it (at least) twice already and just today began reading it again. Then again I’m always into stuff that most people would just find mind-numbingly boring.
3.2.0-17.27 seems to be interchangeable with 3.2.0-17.26 in what I described above, i.e. no change wrt. this bug.
(Then again, I could be completely wrong about your motives, and you could be just after some cheap kicks after all, but I only have what you’ve written as basis and I don’t think you’ve ever hinted of being just after something as petty as sexual satisfaction.)
