Hello!
There is strange behavior of my server. If somebody is pulling very large
file (2-3G) thru samba or grepping the entire ports tree over nfs, server is
going into "suspend mode" (or similar) after 5-10 minutes of work and stops
responding until I strike a key on its keyboard. System clock is not being
updated and left in pre-suspend state. When I boot with non-SMP kernel
problem disappears.

I'm using GA-6BXDS mobo, two P-II 350MHz and 3Com 905B-TX NIC. Any help would
be greatly appreciated.
