Hi, i am using an ASUS P5AD2Premium Board with a P4 3,4 LGA 775 CPU. This one has got 2 Gigabit PCI Express Ethernet cards on-board. lspci 0000:02:00.0 Ethernet controller: Marvell Technology Group Ltd. Gigabit Ethernet Controller (rev 15) 0000:03:00.0 Ethernet controller: Marvell Technology Group Ltd. Gigabit Ethernet Controller (rev 15) both 2 are working, but when i load the driver modules i get 2 unrecoverable PciExpress Hardware failures. Drivers are not implemented in the Kernel Mainstream but as syskonnect told me, already send to the devs. Driver version from syskonnect is v 7.09 obtainable @ http://www.syskonnect.com/syskonnect/support/driver/htm/sk9e21_lin.htm help is appreciated. just mail me for more information if needed. regards marcel
