DM385: REISZER OVERFLOW OCCURED: RESTARTING

Hello,

We are using DM385 custom board with IPNC 3.5. We are occasionally facing REISZER OVERFLOW OCCURED: RESTARTING  issue.

 For that reason i changed below changes but no luck to solve the issue.

1. Increase the bandwidth

/opt/ipnc/init.sh

./bin/sys_pri.out --L3-bw-reg-set HDVICP0 0 0 900 2500&
./bin/sys_pri.out --dmm-pri-set ISS 0&
./bin/sys_pri.out --dmm-pri-set HDVICP0 1&

2. I have back-ported below patch

Can someone help us to solve the REISZER OVERFLOW OCCURED: RESTARTING issue?
