Hi @jyijyi ,  
I will try local\_irq\_disable and enable and will update you . Onto the priority change  
I have changed the priority in spi.c as shown below

**struct sched\_param param = { .sched\_priority = 51 };**

but when observed in the device it was still showing 50

**ps -eo pid,pri,rtprio,cmd | grep mcp**  
**9377 90 50 [irq/131-mcp251x]**  
**9378 39 - [mcp251x\_wq]**  
**10167 19 - grep mcp**

Am i going in the right direction ?
