Hi All,<br>
<br>
Hope someone can help. I just installed 9.04 on a T61p, everything<br>
worked fine for a while but suddenly I was getting 3 minute delays at<br>
startup. After digging into the logs I found that:<br>

So it looks like lp module is hanging there because it can't find a<br>

<br>
So I see two ways of fixing this, to blacklist the modules or to build a<br=

custom kernel.<br>
<br>
The first one does not work. I have created a file<br>
/etc/modprobe.d/blacklist_custom.conf with:<br>
blacklist lp<br>
blacklist parport<br>
blacklist ppdev<br>
<br>
And then ran:<br>
sudo dpkg-reconfigure linux-image-$(uname -r)<br>
sudo update-initramfs -u<br>
<br>
But after rebooting it is still loading the modules.<br>
<br>
The second option of building a custom kernel, well I'm not very<br>
familiar with that and find it a bit scary. I would prefer to go back to<br=

8.10 before doing this.<br>
<br>
Does anyone know how I can fix this?<br>
<br>
Thanks,<br>
