dhcp - strange behaviour in vlan

Hello,

I have a issue with a specific laptop.When it gets plugged into  vlan x I can see port-security errors! If i remove port-security config from the port it wont get an dhcp.

If I change the port to vlan y it works straightaway with or without port-security!

Testing further, we tried other laptops and it works fine with or without port security in vlan x.

Any ideas?!?

Cheers
