I have upgraded to VirtualBox-3.2.4. However, Page Fusion still causes kernel oops ramdomly on my Fedora 12 x86_64 host. I try to run two Windows 32bit guests. One is Windows XP 32bit, the other is Windows Server 2003 32bit. They are the same. <div>
<br></div><div>Not long ago, I wrote a post to here but no one replied to me. Should I post a bug report? </div><div><br></div><div>My post is here: <a href="http://vbox.innotek.de/pipermail/vbox-dev/2010-May/002804.html">http://vbox.innotek.de/pipermail/vbox-dev/2010-May/002804.html</a><br>
