I guess that the debug printing would go out of hand as well, 970<br>
characters printed into the console is no fun either. The test needs a<br>
bit more than just bumping the number of pages. However as we are<br>
getting really close to release I guess that the best course of action<br>
would be workarounding the issue for now by bumping the number of pages<br>
to something as 128 pages. Then we can rework the test once LTP has been<br>
released.<br></blockquote><div><br></div><div><div class="gmail_default" style="font-size:small">OK for me.</div></div><div><br></div></div>-- <br><div dir="ltr" class="gmail_signature"><div dir="ltr"><div>Regards,<br></div><div>Li Wang<br></div></div></div></div>
