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 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?
