ReadyNAS Pioneer Pro BUG: Unable to handle kernel null pointer dereference at (null)
Hello, I have not been using my ReadyNAS Pioneer Pro because I have four other Netgear NASs and this NAS has been problematic in the past. Since the NV+ can not be upgraded to OS 6, I decided to re...
According to one online site, here are the specs of my current memory:
I went through my spare memory and grouped them by type (DDR2, DDR3, etc.). Since the old memory is DDR2, I am going to assume that I must use DDR2 for this NAS. The DDR2 memory that I have, looks like this:
I have at least 2 memory sticks for each of these types of RAM. The first one provides the most (4GB) total memory. Those say NVIDIA SLI on them and are new. However, those are "DUAL channel" memory and at this posting in the Netgear forums:
Fastfwd says the memory in the Netgear Pioneer Pro must be "single channel memory". Is that correct?
Would you recommend using any of this RAM in the Netgear Pioneer Pro?
If not, can you point me to RAM that is compatible with the Pioneer Pro that I can buy?
The below memory:
is $10.98 for 4GB, has the same (as the existing NAS memory) PC-5300 bus type, same 667MHz data transfer rate, etc.; but is "dual channel". So I need to know if that can be used or not before buying any RAM.
I also have 4 spare PCs (which still have their RAM in them) in my PC graveyard, but those are most likely PC3 or greater. Thanks for any advice on this.
"Dual channel" is a designation for a motherboard, not RAM. The ReadyNAS motherboard is not dual channel, meaning you get no advantage upgrading both DIMMs over a single one and that you can use unmatched ones. But that has no bearing on the memory architecture. If RAM is labeled "dual channel", it just means it's sold as a matching pair or DIMMs.
That chain does say the RAM must be "dual rank". What is more important is that you need what is often referred to as "low density" RAM and is shown as 2Rx8 (as opposed to 2Rx4). High density (2Rx4) RAM is often sold as "AMD only" (which is not accurate, as some Intel systems do support it), but I have no idea what your NVIDIA RAM is (a moderator has not yet made the photo visible). Both of these, BTW, are dual rank (the 2R part).
All,
I ordered the below memory:
https://www.amazon.com/gp/product/B07PV86HJQ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
The memory is 2Rx8 and will take me from 1GB to 4GB. I will report back after the memory is installed and tested.
All,
The new RAM arrived and was installed in the NAS. There are only two DIMM slots in the NAS so I removed the existing 1GB DIMM and added the two 2GB DIMMs. I used a grounding strap and had the NAS unplugged when I installed the RAM. When I powered the NAS on, it just said READYNAS on the display and an endless row of tick marks (sometimes it just says READYNAS and other times I get an endless row of tick marks - as explained in the posting in the link above). Therefore, the RAM does not resolve the issue.
I did test the RAM via the "Boot Menu" and it passed for three passes. It took 3.5 hours, but it passed fine. I also ran DIAGs via RAIDAR and that showed no issues as well (minus the old kernel message in the title to this thread).
I am pretty confident that the issue is not:
- the drives (all tested with SEATOOLs in a PC and checked for firmware updates before being installed in the NAS)
- the RAM (new RAM does the same thing)
- the power source (outlet - tried different outlets and outlets on different breakers in different rooms)
- the powerstrip (tried it without the powerstrip when the NAS was located in a different location)
- the UPS (the problem existed before the UPS was installed)
- the 3V internal battery (replaced it)
The NAS is currently plugged directly into the UPS, but the UPS is not the issue.
The motherboard is a FLAME6 VER:1.1. I am not sure if there are firmware updates for that or not.
Most of the time, when the power is disconnected, it will do this once or twice. If the power is not disconnected, it only does this occassionally.
I did replace the power supply with the same model power supply that is in the NAS. Since I would want the replacement power supply to stay in the NAS, I would be willing to try a different model (perhaps one with more Watts). The current NAS power supply is a Sea Sonic Electronics, Model: SS-300SFD Active PFC F3. It is a 300 Watts power supply. The issue existed with the origional NAS power supply as well.
One other person in this thread mentioned that they have the same problem with their Pioneer Pro, so it is not just my NAS that has this issue.
I could get out the VGA cable and look for anything on the console. I have not done that since I upgraded to OS 6.10.4 or since my original posting in the link above. Any advice would be appreciated. At least I went from 1GB RAM to 4GB RAM for $17.48. That seemed worth my time and money. Have a great day.
