It’s more a symptom that Xorg restarts again and again. In my point of view the changes for BookE machines in the PowerPC updates are responsible for this issue.</span><br></blockquote><blockquote type="cite"><span>Bisecting costs a lot of time and I don’t have time for my main work anymore.</span><br></blockquote><blockquote type="cite"><span>Bisecting is good but sometime you have to check your code yourself.

But it provided us good information anyway and I'm sure we could progress quickly if you can do the few tests I suggested in my last email:</span><br><span></span><br><span>- Can you check that 887f3ceb51cd with cherry-picked 525642624783 has Xorg working ?</span><br><span>- Can you bisect between 887f3ceb51cd[good] and 56bec2f9d4d0[bad] to identify first bad commit that stops after loading the dtb and uImage ?</span><br><span>- Once that first bad commit is identified, can you check whether the preceeding commit with cherry-picked 525642624783 has Xorg working or not ?</span><br><span></span><br><span>Thanks</span><br><span>Christophe</span><br></div></blockquote></div></body></html>
