[64studio-devel] IRQ-23 process

[Steve A]

hello Lee

Thanks for the pointer to help trace the problem!


tux at 64studio:~$ cat /proc/interrupts

I've rebooted a few times, and it appears that the IRQ associated with eth1 
(either 23 or 21) is always 3% CPU busy.  Sometimes the machine boots with 
eth1 on its own interrupt, which is why I'm so sure.  Also I'm getting no 
network traffic showing on the router.

This does not happen with the earlier Kernel 2.16.19.1

I'm out of my depth now, I'll create a ticket because I can create this 
every time, and it is new for this kernel.
