Redhat 6.2 locks up during boot when the PowerEdge C410x is connected



Article summary: This article describes how to resolve an issue where RHEL 6.2 locks up during boot while connected to a PowerEdge C410x.


Issue:

A system with an Nvidia HIC card will boot into the OS without error if the PowerEdge C410x is disconnected or powered off but locks up immediately after POST if the C410x is plugged in and powered on. The red loading bar may start to load but halts almost right away. If the server is booted to single user mode, an error about the nouveau driver is displayed rather than the graphic loading bar. Issue has been seen with both M2090 and M2070-Q GPGPUs.

The nouveau video driver that is installed by default in the Redhat kernel is not compatible with the Nvidia GPGPU Tesla cards.
In most cases the nouveau driver should not be activated for an incompatible device.
The nouveau driver needs to be blacklisted in the OS prior to connecting the C410x and Tesla cards. Power the system up into the OS and perform the following steps:

1) Open the /etc/modprobe.d/blacklist.conf file and add the line "blacklist nouveau" to the end of the file.
2) Open the /boot/grub/grub.conf file, find the line that starts with "kernel" for your active kernel and add the option "nouveau.modeset=0" to the end of the kernel boot line.

Save all changes and reboot the server. Properly connect the C410x and power the system back on then install the Nvidia drivers and CUDA software suite.
