Happy new year ! We have a SuperMicro server with a LSI MegaRAID 9260-4i controller. Since Centos 6.6 update (kernel 2.6.32-504), the controller doesn't initialize at boot. Reverting to kernel 2.6.32-431 allows server to boot fine. The server can't boot due to a bug in LSI megaraid module. Boot log ends by a lot of lines: RESET_GEN2: retry=xxx, hostdiag=a4 I tried Centos 6.6
