Thank you, unfortunately 2.6.33-23-realtime amd64 results with 'ACPI:<br>
Expecting a [Reference] package element, found type 0' and a login for<br>
text mode. FWIW I didn't log in and tested to start x or gdm.<br>

</div>This is one of the kernels that stops booting with the message 'mount:<br>
<div class="im">mounting none on /dev failed: No such device.'<br></div></blockquote><div><br></div><div>I have such message too but it is not stops booting and not affects my work. I have no idea what is this exactly :)</div>

</div>Is your machine an AMD dual core too and is the architecture of your 64<br>

Perhaps it has to do with the NVIDIA graphics? Perhaps I should generate<br>
a xorg.conf by running 'sudo X -configure' and test the vesa driver. I<br>
dunno.<br></blockquote><div> </div><div>Yes, I have NVIDIA videocard and it is the reason why I still use 2.6.31 kernel -- it still works with this kernel.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
The eye-catching thing regarding to 'mount: mounting none on /dev<br>
failed: No such device.' is<br>
<div class="im"><br>
# cat config-2.6.31-11-rt | grep CONFIG_DEVTMPFS<br>
# cat config-2.6.32-23-preempt | grep CONFIG_DEVTMPFS<br>
CONFIG_DEVTMPFS=y<br>
CONFIG_DEVTMPFS_MOUNT=y<br>
<br>
</div>that there's no output for 2.6.31-11-rt.</blockquote><div><br></div><div>May be this is a good point. But I don't dig with it, just stop to use new kernels temporarily and still using 2.6.31-rt</div><div><br>
</div><div>One more significant(for me) reason for still using 2.6.31, except nvidia-problem, is that I find out that command ps output was somehow changed in subsequent kernels, so steps starts from 3 from <a href="http://subversion.ffado.org/wiki/IrqPriorities">http://subversion.ffado.org/wiki/IrqPriorities</a> is not working.</div>
