OS X 10.8.5 and OWC Mercury Accelsior PCIe SSD Issue (Kernel Panic from Sleep)

Late in the game Apple made some kind of change in OS X 10.8.5 that affects some Mac Pro systems with the OWC Mercury Accelsior PCIe SSD.

I updated to 10.8.5 right away; I run dual Accelsior E2 cards in my main workstation, I sleep it every night and multiple times during the day—no issues. I have a 3rd Accelsior in a 6-core Mac Pro—no issues. So I have nothing to report from my own experience.

But my cards are the new 'E2' version, so that appears to explain the problem free operation (newer firmware).

Here is the information I have on the issue, direct from OWC.

9/25/2013 update

re Accelsior PCIe SSD cards with 'MARVELL Raid VD 0' System Profiler reported identity.

Limited to Accelsior cards shipped prior to 8/15/2012 at the latest and that can be identified in About This Mac / Apple System Profiler:
Accelsior PCIe SSD cards with 'MARVELL Raid VD 0' under SATA devices.
if it reports Accelsior, then your card is not affected by this 10.8.5 bug.

Current recommendations are to either return to 10.8.4 OS revision or disable sleep. No other issue outside of wake from sleep occurs and this issue is unrelated to our Accelsior driver.

It is attributable to what we have reported as a bug to Apple specific to how the 10.8.5 interacts with a specific Marvell SATA controller chipset firmware revision (affects any product using that controller).

We anticipate a solution in the near future that will be applicable in the field with no requirement to send the card in.
