TDA4VM: After running on the board for a period of time, it occasionally hangs

Part Number: TDA4VM

The board hangs with the following error:

[11616.108612] PVR_K:(Error): 207: CheckForStalledCCB (force): CCCB has not progressed (ROFF=32704 DOFF=0 WOFF=224)

for "TA-P946-T976-SVCamer]

[11616.126162] PVR_K:(Error): 207: CheckForStalledCCB (force): CCCB has not progressed (ROFF=45864 DOFF=45864 WOFF=46368)

for "3D-P946-T976-S]

the setup currently under test:

1、 default PSDK8.4

---> yes

2) SPL (uboot) booting

---> No, SBL booting (SBL + can_boot_app_mcu_rtos + kernel)

3) No any other extra changes/patches than the out-of-box release

---> No, some changes adapt to our own board, such as 2G DDR, SGMII for ETH and so on.

4) Configure the

Linux kernel from default 4KB page size to 64KB page size

---> No, default 4KB page size, and 64KB page size is testing.

We are already experimenting. Current latest status: Since last night, there has been no collapse phenomenon.

We will continue to observe for a few more days. If there is no problem, we will organize this issue to you.
