Re: [CentOS] Hardware raid LSI Megaraid not working since Centos 6.6

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 :-(

My workaround is to install kernel-lt from elrepo repository. It seems to work well.
