I'm using original toolchain that came with development for Viper board =
from Arcom. That probably was time of 2.4 kernels...
Trouble with upgrading of toolchain I'm afraid of - is that all =
packages, libraries etc., that I used thus far with our embedded =
application will become obsolete and will need to be recompiled with =
this new compiler.

As to my first problem with assigning of general interrupt handler to =
chained irq acknowledgment, I'll try to change my code to go with it, as =
my real-time handler for chained interrupt does actually call some =
'acknowledgment' that is based on general interrupt handler. It's just =
it took quite a time to figure out weird behaviour of my application =
when=20
I switched to new Xenomai and couldn't find any info about how Xenomai =
changes chained interrupts handling. That caused some frustration. May =
be there should be some sort of Howto about it on Xenomai site?

Thanks a lot for you help.

Best regards,

Ivan
