Hello,
I am porting the Android Nougat on imx6d processor. I am getting the errors as follow on kernel terminal output,
INFO: rcu_preempt detected stalls on CPUs/tasks:
0-...: (4 GPs behind) idle=f93/2/0 softirq=146248/146249 fqs=51465
(detected by 1, t=102982 jiffies, g=50694, c=50693, q=861)
Task dump for CPU 0:
swapper/0 R running task 0 0 0 0x00000002
[<c0c5e078>] (__schedule) from [<c1300000>] (init_thread_union+0x0/0x2000)
and the device is stuck.
Is it a kind of known issue, for which there is any patch to be picked up ?
Thanks,
Taehyuk
Hi Igor,
I am using the same version. I have run the memory testing, resulting no errors.
The kernel was picked up around Oct. last year, 2018. Do you have any patch i can try ?
Thanks and Regards,
Taehyuk
Hi Taehyuk
could you try to reproduce issue on NXP Sabre reference board.
Best regards

Hi Taehyuk
one can try latest Nougat N7.1.2_2.0.0, L4.9 kernel, rebuild all from scratch.
Also may be useful to check memory:
