You mean when you run evolution the box hangs up completely? (you can't
kill X, switch to another console etc.)
If that is the case, we need the console output when that happens, it
will indicate what goes wrong. Make sure you boot with nmi_watchdog=1
I'm sending you the recommended solution, requires two computers:

This module logs kernel printk messages over UDP allowing debugging of
problem where disk logging fails and serial consoles are impractical.
It can be used either built-in or as a module. As a built-in,
netconsole initializes immediately after NIC cards and will bring up
the specified interface as soon as possible. While this doesn't allow
capture of early kernel panics, it does capture most of the boot
process.
It takes a string configuration parameter "netconsole" in the
following format:
[EMAIL PROTECTED]/[<dev>],[tgt-port]@<tgt-ip>/[tgt-macaddr]
where
src-port source for UDP packets (defaults to 6665)
src-ip source IP to use (interface address)
dev network interface (eth0)
tgt-port port for logging agent (6666)
tgt-ip IP address for logging agent
tgt-macaddr ethernet MAC address for logging agent (broadcast)
Examples:
linux [EMAIL PROTECTED]/eth1,[EMAIL PROTECTED]/12:34:56:78:9a:bc
or
insmod netconsole netconsole=@/,@10.0.0.2/
Built-in netconsole starts immediately after the TCP stack is
initialized and attempts to bring up the supplied dev at the supplied
address.
The remote host can run either 'netcat -u -l -p <port>' or syslogd.
WARNING: the default target ethernet setting uses the broadcast
ethernet address to send packets, which can cause increased load on
other systems on the same ethernet segment.
NOTE: the network device (eth1 in the above case) can run any kind
of other network traffic, netconsole is not intrusive. Netconsole
might cause slight delays in other traffic if the volume of kernel
messages is high, but should have no other impact.
Netconsole was designed to be as instantaneous as possible, to
enable the logging of even the most critical kernel bugs. It works
from IRQ contexts as well, and does not enable interrupts while
sending packets. Due to these unique needs, configuration can not
be more automatic, and some fundamental limitations will remain:
only IP networks, UDP packets and ethernet devices are supported.
