Connecting a pcie at 141a0000.pcie: leads system to hang at platform/drivers/mailbox/mail_mach.c

Hi, We are trying to connect NVIDIA Jetson Xavier NX Developer Kit with custom carrier board to another SoC. Xavier as rootcomplex and other soc as endpoint. Connecting both SoCs leads to an error loop in mail_mach.c , apparently part of bpmp code. Could you give us a hint on what is this warning and why may it be triggered? we are using JetPack 4.6.1 [ 5.951594] iommu: Adding device 0004:01:00.0 to group 59 [ 5.956732] pci_bus 0004:01: pci_scan_slot [ 5.960754] tegra-pcie-dw …

but above answer can not reslove the bug.

with my custom carrier board,with the same kernel and dtb and rootfs.,
the jetpack32.5.0 + XarvierNX 8GB module not print the error log,and work good.
but the jetpack32.7.2 + XarvierNX 16GB module is print follow error log.
