Titolo: Problemi con scheda di rete PCI

Ciao a tutti,
scusate la lunghezza del post, ho un problema stranissimo, e ne sto 
uscendo matto, spero tanto riusciate a darmi una dritta…
ho un debian etch (4.0r1) appena installato, su un HP ProLiant ML110 G4 
(Intel Xeon CPU 3040 @ 1.86GHz, dual core a 64 bit) con due NIC e un 
semplice routing tra le due schede con iptables (LAN e WAN).
Ebbene, ogni qualche minuto imprecisato (mezzora, un'ora, 3 minuti, 
casuale), la scheda di rete PCI aggiunta non risponde più, e il server 
smette di rispondere sulla WAN.
A nulla serve `ifdown eth1` oppure `ifup eth1`, per riattivare la scheda 
devo dare necessariamente:
/etc/init.d/networking restart
al che tutto riprende per miracolo, fino alla successiva e certa 
interruzione.
Durante il "blocco", facendo mmi-diag sulla scheda incriminata, vedo che 
è tutto ok:
=====
Basic registers of MII PHY #32:  1100 782d 0000 0000 01e1 45e1 0001 0000.
  The autonegotiated capability is 01e0.
The autonegotiated media type is 100baseTx-FD.
  Basic mode control register 0x1100: Auto-negotiation enabled.
  You have link beat, and everything is working OK.
  Your link partner advertised 45e1: Flow-control 100baseTx-FD 100baseTx 
10baseT-FD 10baseT, w/ 802.3X flow control.
    End of basic transceiver information.
=====
Anche con ifconfig è tutto ok (ho modificato qui gli IP pubblici):
=====

           inet addr:88.77.88.99  Bcast:88.77.88.103  Mask:255.255.255.248

In /var/log/kern.log vedo però:
Nov 30 13:55:28 debian kernel: PM: Writing back config space on device 
0000:04:00.0 at offset 1 (was 100506, writing 100106)
Nov 30 13:55:28 debian kernel: PM: Writing back config space on device 
0000:04:00.0 at offset 1 (was 100506, writing 100106)
===============================================================
1) ho pensato a un problema di scheda di rete, l'ho sostituita con con 
altre tre di marca diversa (D-Link, USR) anche se con chipset simile 
(RTL8139C, RTL8139D,…), e il comportamento è stato identico
2) ho un altro HP ProLiant identico e imballato, e ho replicato la 
configurazione di debian, provando le diverse NIC, comportamento identico
3) Ho provato ad aggiornare il kernel, con il 2.6.22 ma
il problema è lo stesso…
4) ho pensato che ci fosse qualcosa legato al risparmio energia, e ho 
rimosso acpi e simili, dando acpi=off come opzione di boot: nulla.
5) ho cercato in Google usando "kernel PM Writing back config space on 
device offset was writing" come stringa e trovo una marea di risultati: 
gente che ha lo stesso problema con fedora, debian, suse, che chiede 
aiuto e nessuno che gli risolva la cosa
Ragazzi, sto uscendo matto... vi prego datemi una dritta, un idea, uno 
spunto... non so più cosa fare...

La butto la solo perché sei alla frutta :)
Non è che hai installato gnome su quel server? e magari non è che con 
gnome hai anche questo bel demone: /usr/sbin/NetworkManager?

Mi hai dato lo spunto per completare il quadretto e aggiornarvi sugli 
ultimi sviluppi:
- debian è installato al minimo: durante l'installazione da DVD, al 
momento del tasksel, non solo non ho installato ambienti desktop, server 
vari ecc., ma non ho neanche selezionato "software di base" (vado a 
memoria, per la dicitura...). I vari pacchetti li ho installati dopo 
(squid, dansguardian, apache2, bind9, dovecot, postfix, horde3, ecc.)
- mi è venuto un dubbio atroce: e se non fosse problema della scheda di 
rete, ma del routing tra le due? Pensavo al fatto che riavviando i 
servizi di rete, di fatto riavvia anche l'ip_forward
Ho fatto una cosa: in /etc/network/interfaces ho disabilitato la eth0 e 
il routing, e ho lasciato semplicemente la scheda di rete PCI (eth1) 
come scheda unica e sola con IP pubblici statici. Finora (45 minuti) sta 
andando tutto bene senza interruzioni. Se la prova dovesse andar bene, 
significherebbe che la scheda di rete, il PCI e gli interrupt e irq vari 
non c'entrano nulla, ma è questione di problemi nel routing software 
(bug??). Farò sicuramente la prova di aggiornare a "testing" l'intera 
installazione... dopodiché, in caso negativo... che fare?
Come ne esco da tutto ciò??
Tutto questo mi sembra assurdo...
Grazie intanto...
Gabriele


-cut-
hai il demone avahi in funzione? 

 questione...
mai sentito parlare di quoting, suppongo
Ciao
Stefano 

 hai il demone avahi in funzione? 
No...
Dalle altre prove che ho fatto sembra proprio che il problema si 
manifesti quando è attivo il routing tra eth0 e eth1.
Ho fatto la prova di disabilitare la eth0 (incorporata nella scheda 
madre) e lasciare solo la eth1 con IP statici pubblici.
Tutto è filato liscio, e il server è stato sempre raggiungibile.
Qualche componente bacato in etch (4.0r1)? Ho reinstallato lo stesso 
sistema minimale aggiornando tutto a "testing". Nulla, stesso problema.
Con sistema minimale intendo installazione di debian da DVD di 4.0r1, e 
al momento della scelta tasksel, deselezione di tutte le voci, nessun 
ambiente destop, nessun server, neanche l'ultima voce ("software standard").
Ho rinunciato a qualsiasi pacchetto aggiuntivo (webmin, 
squid/dansguardian, php/mysql, ecc.) ad eccesione di apache2, che uso 
per testare il caricamento della pagina anche da fuori l'ufficio (è più 
pratico che provare via ssh): apro un browser e carico una pagina html 
impostata con un auto-refresh di alcuni secondi: trovo immancabilmente 
errore di timeout dopo alcuni minuti.
Sono scoraggiato...
Possibile che un sistema pulito appena installato al minimo dia questi 
problemi?
Possibile che sia l'hardware HP a essere il problema? Abbiamo 8 server 
uguali in ufficio e su 3 di essi appena sballati si manifesta il problema…
Possibile che linux sia così schizzinoso e dipendente dall'hardware 
(dando per buona l'incompatibilità con i miei HP)?
Possibile...?? :-((

 Innanzitutto potresti postare un "lspci" della macchina in questione...
L'avevo già postato, ma non mi ero accorto che non era arrivato. Avevo 
messo un file txt in allegato...
