Tesla K80 (Dell R730), Centos 7: Only one gpu shows up, hardware problem ?


I have a K80 in a PE R730 on Centos 7. At first it worked great then suddenly only one GPU shows up, the second one has completely disappeared. The K80 was cohabiting with a K40 (From Nvidia, not Dell). I have removed the K40, same issue. I have switched the PCI-E bus (from CPU 1 to 2), same issue.
Thanks for any help.
