This looks weird to me:

0x00005a58:      0x11000001: MI_LOAD_REGISTER_IMM
0x00005a5c:      0x00012044:    dword 1
0x00005a60:      0x0043b625:    dword 2

0x00005a6c:      0x0043b625:    dword 2
0x00005a70:      0x10800001: MI_STORE_DATA_INDEX
0x00005a74:      0x00000080:    index

0x00005a80:      0x0b160001: MI_SEMAPHORE_MBOX compare semaphore, use compare
reg 2
0x00005a84:      0x0043b625:    value
0x00005a88:      0x00000000:    address
