This is likely (almost certainly) a hardware issue. However, I would like any guidance available on diagnosing the exact cause and remedy.

We have a warm standby server then went off line over the weekend. The problem manifests itself as a kernel panic during the centos boot process. The issue appears to be with auto-mounting a number of pci devices. Unfortunately the error messages scroll off the monitor that I attached to it. This is some of the residue text that I though might have some use in diagnosing the problem.

Kernel panic not syncing: Fatal exception Comm pciehpd Tainted: G DW -- ------- . . .

drm_k,s_helper panic occurred switching back to text mode.

At which point the system is non-responsive.

Any ideas as to what is going on? Any other information I should be looking for?
