Very strange result.
I am don't see in you output any chelsio irq, like this:
irq289: t5nex0:evt 2 0
irq300: t5nex0:1a0 204093767467 48085
irq301: t5nex0:1a1 204536605147 48189
irq302: t5nex0:1a2 204677310714 48222
irq303: t5nex0:1a3 204727624595 48234
irq304: t5nex0:1a4 204345362150 48144
irq305: t5nex0:1a5 203085398725 47847
irq306: t5nex0:1a6 204014240537 48066
irq307: t5nex0:1a7 204216351652 48114
irq308: t5nex0:1A0 132806676 31
irq309: t5nex0:1A1 133275327 31
