上妻です。
さらに、いろいろ調べて、わかったのですが、
eth0 をアクティブにする前と後では、/proc/interrupts
に違いがあり、
前
CPU0 CPU1
0: 29785 0 IO-APIC-edge timer
1: 6 0 IO-APIC-edge keyboard
8: 1 0 IO-APIC-edge rtc
9: 0 0 IO-APIC-level acpi
14: 1829 0 IO-APIC-edge ide0
16: 5027 0 IO-APIC-level usb-uhci
17: 0 0 IO-APIC-level Intel ICH4
18: 0 0 IO-APIC-level usb-uhci
19: 9605 0 IO-APIC-level libata, usb-uhci
20: 0 0 IO-APIC-level Ricoh Co Ltd RL5c476 II (#2)
21: 4 0 IO-APIC-level ohci1394
23: 1634 0 IO-APIC-level usb-uhci, ehci_hcd, Ricoh Co
Ltd RL5c476 II
NMI: 0 0
LOC: 29706 29708
ERR: 0
MIS: 0
後
CPU0 CPU1
0: 243083 0 IO-APIC-edge timer
1: 6 0 IO-APIC-edge keyboard
8: 1 0 IO-APIC-edge rtc
9: 0 0 IO-APIC-level acpi
14: 18821 0 IO-APIC-edge ide0
16: 5027 0 IO-APIC-level usb-uhci, eth0
17: 0 0 IO-APIC-level Intel ICH4
18: 0 0 IO-APIC-level usb-uhci
19: 13611 0 IO-APIC-level libata, usb-uhci
20: 0 0 IO-APIC-level Ricoh Co Ltd RL5c476 II (#2)
21: 4 0 IO-APIC-level ohci1394
23: 15392 0 IO-APIC-level usb-uhci, ehci_hcd, Ricoh Co
Ltd RL5c476 II
NMI: 0 0
LOC: 242985 242987
ERR: 0
MIS: 0
となっていました。
ここで、IRQが、
16: 5027 0 IO-APIC-level usb-uhci
から
16: 5027 0 IO-APIC-level usb-uhci, eth0
に変化するのが分かったのですが、これが、ADSLに繋げることが
できない理由のような気がしますが、どうなのでしょうか。
調べたところ、IRQが原因で、繋がらないことがあるらしいので、
そうではないかと思うのですが。
それから、lspci -v の結果も貼っておきます。
