Problems have been observed in coreint (EPR) mode if interrupts are left pending (due to the lack of device quiescence with kdump) after having tried to deliver to a CPU but unable to deliver due to MSR[EE] -- interrupts no longer get reliably delivered in the new kernel. I tried various ways of fixing it up inside the crash kernel itself, and none worked (including resetting the entire mpic). Masking all interrupts and issuing EOIs in the crashing kernel did help a lot of the time, but the behavior was not consistent. Thus, stick to standard IACK mode when kdump is a possibility.
