for xhci, all of these seem to be the same issue and it
appears to be a "high level allocator doesn't know what
it is allocating and does not align properly". the
problem is likely:
#define XHCI_TRB_ALIGN 16
struct xhci_trb {
...
} __packed __aligned(XHCI_TRB_ALIGN);
which is included in:
struct xhci_softc {
...
struct xhci_trb sc_result_trb;
... how do we convey the structure alignment needed for
softc, or do we fix it by moving it into its own separate
aligned allocation?
