This is often because sctp_assoc_sync_pmtu lacks a __init annotation or the annotation of .LBE1560 is wrong. -- The function sctp_transport_burst_limited() references the variable __init .LBE468. This is often because sctp_transport_burst_limited lacks a __init annotation or the annotation of .LBE468 is wrong. -- FATAL: modpost: The relocation at __ex_table+0x1478 references section ".debug_str" which is not executable, IOW it is not possible for the kernel to fault at that address. Something is seriously wrong and should be fixed.
