ACPI Sleep doesn't work in 2.6.7

An echo "3" >/proc/acpi/sleep entered my laptop in sleep mode only for a couple of seconds (I see it with a del) before return an error in dmesg:

Jun 17 16:02:06 greg-port kernel: PM: Preparing system for suspend
Jun 17 16:02:06 greg-port kernel: Stopping tasks:

After that, I lost network connection until I shutdown my computer.

There are a lot of message concerning network in syslog before rebooting:

Same errors appeared every 12 seconds.

Thank you all for the good work with linux, keep up with it ! :)
