| * Gillies: 88E8055 PCI-E Gigabit Ethernet Controller [11ab:4363], after the "ifopen net0" I have the prompt back and it crashes (Keyboad is blocked, no message). If I am fast enough, I can type 2 or 3 letters on the new prompt before it's blocked. | * Gillies: 88E8055 PCI-E Gigabit Ethernet Controller [11ab:4363], after the "ifopen net0" I have the prompt back and it crashes (Keyboad is blocked, no message).

| * meteger: there are a few PCI IDs in the current tg3 that work fine when you do a tftp or HTTP transfer but fail miserably for iscsi, for some reason. but that driver was ported to etherboot in 2003, and it took 7 years for someone to request that specific PCI ID. | * meteger: there are a few PCI IDs in the current tg3 that work fine when you do a tftp or HTTP transfer but fail miserably for iscsi, for some reason. but that driver was ported to etherboot in 2003, and it took 7 years for someone to request that specific PCI ID. | ||
