I have a server running CentOS 6.0. Last night I replaced the CPU and motherboard. Old hardware: Supermicro x8sil-f + x3440. New hardware: Supermicro x9scl+-f + E3-1230. This is a new Sandy Bridge Xeon.
Everything else remained the same, including an IBM m1015 SAS HBA. This is just an IBM re-branded LSI 92xx-8i (9220-8i specifically I believe), which uses the LSI SAS2008 chipset and the megaraid_sas driver. It worked without any issue on the old motherboard/cpu. However, with the new motherboard/cpu, the system makes it through the BIOS POST without any issue. But about half-way through the kernel initialization, it basically locks up. It will sit there for several minutes, doing nothing, then start printing out error messages (I was unable to get a screenshot or take note of the errors).
But if I take the m1015 card out, the system boots quickly and without issue, as it always has.
I saw this post[1] on the forums, which suggested that Sandy Bridge really needs 6.1, which, for those of us using CentOS, we can only get sorta close to by using the continuous release. So I did a "yum install centos-release-cr ; yum update". I let everything install (there were no install errors or problems), and rebooted with the m1015 in back in the system, but the problem remains.
So now I'm at a loss. Anyone have any thoughts?
