Hallo,

Leider habe ich von Hardware, speziell von Interrupts auf den Intel Kisten nicht allzuviel Ahnung - daher meine Frage:

Auf meinem Server (älterer PC mit Athlon XP mit ASUS Board :evil: ) habe ich (wie auch auf den anderen Rechnern) gentoo installiert. Alles lief soweit gut. Dann kam ich auf die Idee, eine PC Karte mit USB 2 Adaptern einzubauen. Seit dem Tag verliert der Rechner IP Pakete. Ich habe die Karte wieder ausgebaut, aber es hat sich nichts geändert (kernel war immer derselbe, 2.6.25-gentoo-r7). Da der Rechner gleichzeit als Router / Gateway zum Internet dient, ist das nicht so berauschend:

Code:
$ ping -c 30 lotte
. . .
--- lotte ping statistics ---
30 packets transmitted, 27 received, 10% packet loss, time 28997ms
rtt min/avg/max/mdev = 0.226/0.258/0.294/0.027 ms


Die usb Karte ist jetzt nicht drin:
Code:

Ich habe lange zurückreichende Backups von /etc, kann man vielleicht einfach eine Datei zurückspielen oder vergleichen? (Leider habe ich nichts gefunden - aber ich bin hier auch nicht gerade mit übermäßigem Wissen gesegnet :oops: .)

Vielen Dank, ixo
