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 install disk and it also fails to find disks but Centos 7 install disk boot fine. It's annoying to be stuck at 2.6.32-431 kernel and I have no idea how to solve this issue :-( Thanks for any help. -- Philippe BOURDEU d'AGUERRE AIME - Campus de l'INSA http://www.aime-toulouse.fr/ 135 av. de Rangueil Tél +33 561 559 885 31077 TOULOUSE Cedex 4 - FRANCE Fax +33 561 559 870
