program blocks at clFinish

[yangdx2022]

We built our project on an A10 platform using AOCL 19.1.0.240, with kernel 4.19.261 and CentOS Linux release 7.9.2009. The program works on another server with the same AOCL version, same AOCX, same program, and same kernel. However, after moving the disk that saved the entire system to the current system, it blocks at clFinish. We observed that it calls sem_wait from acl_wait_condvar, and there are no errors or segfaults in dmesg. Could this be caused by not calling acl_signal_device_update? When is acl_signal_device_update called? Could it be a loose contact issue? Are there any extra information need to provided.
