The dmesg you sent does not correspond to /proc/interrupts and /proc/irq.
Anyway, you have:
[ 3.345790] Xenomai: SMI-enabled chipset found
[ 3.345851] Xenomai: SMI workaround failed!
So, you may have an issue with SMIs.
And you have this:

So, your system is running without an IRQ for three drivers. This may
cause, say, the keyboard driver to be in "polling" mode, and so appear
to be very slow.
