Hi Hao,
Yes UsbHcUnlinkMemBlock() call should be uncommented.
--
for (Block = Pool->Head->Next; Block != NULL; Block = Pool->Head->Next) {
UsbHcUnlinkMemBlock (Pool->Head, Block);
UsbHcFreeMemBlock (Pool, Block);
}

UsbHcFreeMemBlock()->IoMmuFreeBuffer()->mIoMmu->FreeBuffer(), which may end up
calling PeiFreePages() depending on gEdkiiIoMmuPpiGuid implementation. Surely
both will work since UsbHcFreeMemPool() can't be interrupted by any service
call to use the memory just

Yes, it is the same issue discussed in
https://edk2.groups.io/g/devel/topic/92833071#92165
MdeModulePkg\Bus\Pci\XhciPei\UsbHcMem.c
for (Block = Pool->Head->Next; Block != NULL; Block = Pool->Head->Next) {
// UsbHcUnlinkMemBlock (Pool->Head, Block);
