supposedly in user space then it will break things. Another possibility is
just that you're running out of RAM, or that

This is on Freescales code base on the 5485 right?
(That is an old kernel...)
Yes it is.
Lots of interrupts means lots of context switches, into and out
of the kernel. If there is any bugs in the entry or exit code
that interferes with the running
Hi
I'm using Linux Kernel 2.6.10 for Coldfire 5485 in an embedded application.
I developped my own device-driver (Profibus), working on the internal
UART of the coldfire.
This Driver produces heavy hard-interrupt und soft-irq load, because
UART Data is received and transmitted with 93750 bit/s.
