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
