When I warm boot the DG41TY the Realtek NIC(RTL8111D) sometimes disappears...
It is not detected by the linux Debian OS. (pci config space reads 0xFF for the NIC "lspci -x"!!!!)
I'm currently using Debian lenny 2.6.26-1-686.
Cold booting resolves the problem.
Have already tried with latest Realtek driver r8168-8.010.00 and r8168-8.013.00.
BIOS version TYG4110H.86A.0031
