That doesn't make it correct. This same problem occurs in other drivers and the usual trick is to set the pci mask to 32bit, allocate those command buffers ready, then flip back to 64bit. Just be sure one thread doesn't change it to 64bit while another is allocating commands. The reverse is fine since an accidental odd bounce is no big deal
