hi teams:
we are using the 960+953+4 sensors.The sensor output is the same pixel 1920*1080.

we use 960 two ports output data to two csi2 of xavier.

sensorA----------| -------------960 csi2 port 0 --------------- Xavier CSI C & CSI D

sensorB----------|

sensorC----------|--------------960 csi2 port 1---------------Xavier CSI E & CSI F

sensorD----------|

we can open each camera separatly, but 4 cameras cannot be opened at the same time occasionally.
Attached is the kmsg log and trace. Please help analyze the cause of the problem.

Boost the nvcsi/vi/isp clock to try.

sudo su

echo 1 > /sys/kernel/debug/bpmp/debug/clk/nvcsi/mrq_rate_locked
