Problem summary

  • HE, HV8 and HV4 systems reboot at the same time,
    one of the LPARS's IB interfaces will not ping anymore.
    In most of  the cases it was ib1 .
    

Problem conclusion

  • The problem was an interrupt received before the galaxy
    device drivers had the EQ resources ready.
    The problem, we were enabling the interrupts then we work
    on allocating the EQ resources.
    In normal conditions, that is never a problem.
    But in this case, for some reason, the adapter fires an
    interrupt when we were not ready.
    The solution was to first, get all the resources and then
    after the last step possible, enable the interrupts.
