Occasional Visitor
Hey there, I've been running FW386.1 on RT-AC88U since it came out, and just in the last few days I have started receiving the following message in log files:

Code:

Is anyone having the same message? Is this message a standard one or is telling me that I have an issue?

Thanks in advanced!
 
Same issue for me on an RT-AC5300. dirty upgrade to 386.1_2:

Code: 
Feb 15 11:32:50 RT-AC5300-AD60 kernel: udb_ioctl_copy_out: no handler for ioctl 0xd:0x4
Feb 15 11:32:50 RT-AC5300-AD60 kernel: udb_ioctl_copy_in: no handler for ioctl 0xd:0x3

Haven't seen anywhere else on the forum on what causes this, but a few people have posted about it in the 386.1 release thread.
 
In my case I still have errors of that type. I don't know if mentioning the developer in this thread can still help us. In my log also transmission gives me an error. I think everything comes from my HD connected to USB. I will try to remove it to see what happens.

I am getting the same after a dirty update to 386.2 on my RT-AC88U.
 
There is no RMerlin 386.2, yet.
 
lnViztor said:
386.1_2*

It seems that these errors in most cases occur on the ac88u model. ¿Any solution?
Click to expand...
I was about to comment the same but BrettDioson has another model. Anyway, I will do a full restore procedure during the coming weekend to see if I can eliminate these messages
 
Yes, it seems that in the 3200 it also happens. In your case and mine we have the same devices (AC88 + AC68 node). I did a clean install thinking that it would be fixed but I still have those entries.
 
I did finally a hard reset and configure it all over again, and I've uploaded again the firmware (386.1_2) on my AC88U. I installed some scripts such as amtm, diversion and skynet, and I did not face any message for many hours (12 hr. more and less). After that I installed scribe and then I started to see the same messages in my log.... :(
I am pretty sure that scribe has nothing to do with the problem......
 
I did a factory reset 2 days ago and now these messages are re-appearing on the 3rd day
 
Yesterday I uploaded the firmware 384.19 back from firmware 369.1_2 in my router and node, and I am not getting those messages so far (I did a dirty downgrade so same configuration)

Also, I am not experimenting AiMesh nodes disconnections as I was having with firmware 386.1_2 (AiMesh nodes disconnect since 386.1)

Let see the behavior of my connection in the coming days.
 
My log is also flooded with these messages -
