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 retire that NAS and see if I can get the Pioneer Pro NAS working again. I tested six 1TB Seagate drives with all the tests that Seagate's Seatools has (including the long tests which take a long time) and all those tests passed. I also checked for any firmware updates for all of the drives. I then put the six drives in the Pioneer Pro, did a factory reset, and setup the NAS. The RAIDAR diags did find one drive with four spin retries so I swapped that drive out and drilled a hole in that drive so that it would not get used again. The new drive built fine when added to the RAID and then RAIDAR diags were 100% and showed no issues. I setup three backup jobs and ran those to put data on the NAS. I let that run overnight as I figured it would take a while. The next morning, I could not access the NAS via file explorer, could not HTTP to the NAS, and could not ping the NAS. Nothing was on the LCD screen on the front of the NAS. The only thing I could do was poweroff the NAS by holding in the power button. When I powered on the NAS, the NAS was back to it's old tricks where it just says READYNAS on the LCD screen and never tries to boot. The fan for the NAS was running at full speed as the NAS is loud when this happens. This is the same problem that I had with this NAS before which I explained in detail in this posting:
I powered the NAS off by holding in the power button; waited two minutes and powered the NAS back on. The NAS booted fine. There are no new entries in the logs that can be seen via the HTTP admin GUI other then the backups completing that I ran the night before. Recently when I setup the NAS with the factory reset, I upgraded the OS to Firmware 6.10.4. That all worked fine.
The only new message from my previous thread is this is seen in diags with RAIDAR:
2021-01-22 22:13:40: BUG: unable to handle kernel NULL pointer dereference at (null)
The NAS has two NICs that I bonded together with a MTU of 9000 (to use Jumbo Frames). I use CAT7 ethernet cables. The NAS is currently booted and working fine. Since I saw this message on other postings in this forum (and other places online), I thought I would see if this is a OS 6 BUG or perhaps something that could lead me to the final solution on why the NAS does not boot sometimes when powered on and just says READYNAS. A new NAS powersupply is in the NAS (as fully detailed in the above posting). The data on the NAS is fully expendable as I put the same data on all four NASs. Any input would be appreciated. Thanks.

How much memory do you have in the NAS?
Also, do you have any apps installed?
Hello Stephen,
Thanks for quick reply! There are no apps installed on this NAS as I just use the NAS to RSYNC data from the other NASs. It was also just factory reset within the week so it only has on it what you get from that.
As for memory, I never added any memory. It came with 1 DIMM in the NAS. The DIMM is a 1GB DIMM. The memory tests pass that you do through the hardware via the boot menu.
FWIW, I had the same experience with my ProPioneer over the past year. It has os 6.10.4. From time to time, without any entry in the logs or warning, no apps and temperatures OK, it behaves as you describe. I replaced it with a used RN526x. The ProPioneer is now #2 backup to the RN526. (#1 backup is USB that goes offsite regularly).
FYI - The memory that I have in the NAS looks like this:
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.
