This appears appears to be due to a flaky backplane. |
In recent version of the kernel, it appears that the mpt2sas driver was consolidated into mpt3sas. This driver crashes with a SAS2008 adapter while a recent version of the kernel (4.3.3) with the old mpt2sas driver does not appear to crash. Once the crash has occurred (during bootup), the driver disconnects from the adapter and devices can no longer be seen by it.
