Patched boot.img and then device bootloop

Start by reviewing the patch log, especially the kallsyms resolution failures and the warning that CONFIG_KALLSYMS_ALL is not set. The report identifies a vivo PD2168 running Android 11 with kernel 4.14.186 and says the patched boot image bootloops, but provides no crash logs or reproducible test steps. Progress would mean identifying the failure from device logs and reproducing a successful boot with the patched image.

Currently, there is no immediate solution. You need to troubleshoot it yourself or provide the device to me for further investigation.
The device is vivo PD2168(Y10-T1); Try all are Release version then bootloop.
kernel version: 4.14.186
Android 11
--------------------------------------------------------------------

Some kernels hide these functions: commit_creds、sys_call_table、getuid/geteuid,Then device to Crash, are bootloop, I modified the code to make the device work, but still haven't obtained su because vivo has anti ROOT
