Hi Tianyang,<br>
<br>
<div>Default configuration, generally might not boot the system.<br>
Tries to remove redundant modules and only use exactly necessary driver, file system, etc.<br>
Hope this would help.<br>

<div style="">My name is Tianyang Che. I've encountered some difficulties during installing the litmus-rt. I was following the installation instruction provided by the litmus-rt website.</div>

<div style="">I've summarized my method below:</div>

<div>cd $DIR</div>
<div># get Linux 3.0</div>

<div>mv linux-3.0 litmus-rt</div>
<div># apply the LITMUS RT patch</div>
<div>cd litmus-rt</div>
<div>patch -p1 < ../litmus-rt-2012.3.patch</div>
<div><br>
</div>
<div>#as for the configuration file, I just used the sample config which is provided in the website.</div>
<div>make menuconfig</div>

<div>make bzImage</div>
<div>make modules</div>
<div>make modules_install</div>

<div style="">Then when I was trying to get into the new kernel, I always got this initial image.</div>

<div style="">I installed litmus-rt under kernel v3.0. And I used Ubuntu 12.04, both on virtual machine and real computer.</div>

<div>Hi Tianyang,
<div><br>
</div>
<div>Are you able to boot into the vanilla Linux 3.0 kernel without the Litmus patch applied? We should probably figure out if the problem is with the Litmus patch or with the config file. It is most likely the later, but we can try to rule out the Litmus
patch as the cause. The configuration file needs to be tailored to support your system's hardware.</div>
