When reading this I realized this might also be the case why the ns8250 driver was too slow when using isdv4_tablet driver. I hacked around it in the ns8250 driver so that more of the buffer is read in the kernel when processing the interrupt[1], which probably reduced the amount of interrupt notifications that were sent to ns8250.
