kmem_cache_alloc+5c Error on Boot, unable to access NAS

Since I cannot find my box in the autofill list above and there is zero filter capability (yea for Netgear!), here is the Model info straight from the back of my NAS: Netgear Advanced Storage Mo...

Thank you to everyone who assisted me with this issue. The factory reset with a single drive was successful and since I had completed the full back up of the data I went ahead with the factory reset with all four drives inserted. The rebuild took about 2 days but once completed the drive was available and ready for use. I transferred the 3TB's back to the drive and have now been accessing it again as normal prior to this outage. I can also confirm that my default/base/factory set version was 6.5.1 so no extra effort needed there.

After this completely avoidable debacle, I cannot imagine every allowing another firmware update due to Netgear is using this as a way to suck you in and pay for support... :(

I will be setting this issue to resolved. Thank you again everyone!!!

To confirm if the issue is hardware or software, you can use a scratch disk:
1) shutdown the NAS
2) remove and label all your HDDs
3) insert a temporary HDD (it will be wiped)
4) perform a factory default via the boot menu
-> if the NAS boots ok, the other issue is software, not hardware
-> if the NAS doesn't boot ok, and you have the same issue, then you can consider the flash is corrupt. The flash may be considered as part of the hardware...

I didn't read all of your messages, but NETGEAR should have offered a Per Incident contract as well, which is most likely cheaper than a yearly contract.

I tried as recommended and booted up with a single drive and everything booted up fine. RAIDar is also reporting a healthy system and I was able to access the admin site to perform the setup steps with no issues. Based on your directions this clears the NAS of a hardware issue. Since I have already run full diagnostics on all four drives that hardware should also be ruled out.

Is my assumption right that the next step would be to reinsert my original four drives and perform a factory reset on them? All data is now backed up to another source so at this point nothing should be lost other than time for the rebuild and transfer time.

  I'd try the factory reset next, (and if it is downrev, bring it up to 6.5.1 before reloading data).
