ML350e Gen8 BSOD HpCISSs2.sys

I have a newly installed ML350e Gen8, running Small Business Server 2011, that is rebooting from a Bug Check almost every other day; 


The problem seems to be caused by the following file: HpCISSs2.sys



STOP: 0x000000d1 (0x010, 0x00b, 0x000, 0xfffff8800127fa85)


The Smart Array controller (420i) is running the latest firmware, though I have downgraded the Smart Array driver to test (the error was previously exactly the same but referencing HpCISSs3.sys when using the latest driver). 


Has anyone else experienced this, as I could not find anything via searching, or have any idea as to how to resolve it?

Re: ML350e Gen8 BSOD HpCISSs2.sys

I've seen the Advisory, which applies to Server 2012 and not Small Business Server 2011, and have already downgraded from the version of the drivers as they had been generating the same BSOD, not to mention filling the Event Log with HpCISS3s Event id 5009.


HP SUM has been run on the server, so all drivers/firmware should be the latest available from HP.
