This one only has two gige cards: tg3.c:v2.2 (August 24, 2003) PCI: Found IRQ 54 for device 0000:01:04.0 ACPI: No IRQ known for interrupt pin A of device 0000:01:04.0 - using IRQ 54 eth0: Tigon3 [partno(030-1771-000) rev 0105 PHY(5701)] (PCI:66MHz:64-bit) 10/100/1000BaseT Ethernet 08:00:69:13:e6:a7 PCI: Found IRQ 66 for device 0000:11:04.0 ACPI: No IRQ known for interrupt pin A of device 0000:11:04.0 - using IRQ 66 eth1: Tigon3 [partno(030-1771-000) rev 0105 PHY(5701)] (PCI:66MHz:64-bit) 10/100/1000BaseT Ethernet 08:00:69:13:e4:a4 PCI: Found IRQ 53 for device 0000:01:03.0 ACPI: No IRQ known for interrupt pin A of device 0000:01:03.0 - using IRQ 53 As for the dentry and inode-cache tables, yes they're probably too big, and they're also allocated on node 0 rather than being spread out.
