<p>How to address nvidia client with incompatible nvidia kernel modules</p> <p><b>New page</b></p><div>When a Nvidia client updates, we must get the kernel drivers to be updated with it. There are two kernel modules that must be updated. If there is a conflict between your Nvidia client and your kernel drivers check with: dmesg | grep &quot;NVRM&quot; &lt;br /&gt;<br /> dmesg | grep &quot;NVRM&quot;:<br /> <br /> API mismatch: the client has the version 352.93, but<br /> NVRM: this kernel module has the version 352.79. Please<br /> NVRM: make sure that this kernel module and all NVIDIA driver<br /> NVRM: components have the same version.<br /> <br /> Use lsmod and grep for nvidia to find the actual kernel module names:<br /> -sh-4.1$ lsmod | grep nvidia<br /> nvidia_uvm 71483 0<br /> nvidia 8531094 1 nvidia_uvm<br /> i2c_core 29132 2 i2c_i801,nvidia<br /> With this information, I see two kernel modules with the name nvidia in them.<br /> <br /> We can update them manually by doing:<br /> rmmod nvidia_uvm<br /> rmmod nvidia<br /> modprobe nvidia_yvm<br /> modprobe nvidia<br /> <br /> Preferably, we&#039;d have a puppet module automate this task of updating nvidia kernel modules to match the version number of the nvidia client. <br /> Puppet Code: <br /> exec {&#039;unbreak-nvidia-after-driver-update&#039;:<br /> command =&gt; &#039;/sbin/rmmod nvidia_uvm ; /sbin/rmmod nvidia ; /sbin/modprobe nvidia ; /sbin/modprobe nvidia&#039;,<br /> notifyonly =&gt; true,<br /> subscribe =&gt; [Package[&#039;nvidia&#039;]],<br /> }<br /> <br /> [[Category:Sysadmin]]</div>
