Hi @gpluser 
Seems like a new signature, could you please open a support case and let me know the case number?
Please share the AP support file on the case so that I can look into it.

Also, let me know the below details:
1. How many APs are there in the network?
2. Is the issue seen on all AP models are specific Model?

[gpluser]

Hi,

ok, i will open a support case.

1. i have 4 Ap's, R510, R710, T310c and the T610. 

2. Kernel Panic only at T610, with the older firmware at the R710 too.

[gpluser]

Hi again 🙂

the case ID is 01497668

best regards

Hi @gpluser
