Thank you for the PM/ethernet answer, the problem was that EIT didn't
change the grub.conf file and after reboot the server machine startes with
the old kernel.
Unfortunately I have another problem - when I run all mpic++ applications
except for hello.cc (found in examples directory), either in single-, or
multi-user environment, the server machine hungs and I have to switch the
power off to reboot it. hello.cc works, but it takes about 1 min to
execyte it. A compute node writes out a message:
spurious 8259A interrupt in IRQ7
I checked /proc/interrupts on the server and the compute nodes and they
look like:
Server:

How can I find and fix any overlapping?
Thank you in advance for your help
