i've got a server and here's the specs:

intel se7500cw2 (mobo)
intel xeon 2.6 GHz
512 MB (RAM)
2 on-board LAN ports

after successfully installing fedora core 4, the boot up process won't continue. a message is shown during the startup:

Debug: sleeping function called from illegal context at mm/slab.c:1621

after that, my keyboard and mouse won't work anymore. Then i tried installing fedora core 6 on the same machine. but during startup, it's stuck on starting udev. please help me with this problem. what should i do?

thanks guys...
