kernel log neukazuje nič podozrive:
Jan 2 19:40:13 xxxxxxxx kernel: r8169: eth0: link up
v logoch nemam nič podozrive ohľadom dhcp, moju ipadresu mi prideli korektne...
mam kabel - ethernet (Antik - kosice)
v changelogu pre 2.6.32 je tych zmien ohladom r8169 relativne vela....
ten ipv6 este pozriem
modprobe -r r8169a nahraj ho s optionom debug
modprobe r8169 debug=cislo
cislo je 0(nic) az 16(vsetko). A potom pripadne pozeraj hlasky jadra.

ethtool -s eth0 speed 100 duplex fullTady musis jeste: ethtool -s eth0 autoneg off Jenze vypnutim autonegace se ti protistrana nastavi na 10/half a nehnes s ni. Tak to zkus na 10/half. Jinak ja mel s touhle sitovkou priserny problemy taky, pak jsem to vzdal. Vpodstate slo o to ze existuji moduly r8168 a r8169. Vtip je v tom ze realtek nedela mezi jednotlivymi Hw rozdil a tak r8169 obsahuje pciid identifikaci i tech HW na ktere by spravne mel jit r8168. Jenze z toho duvodu se ty moduly navzajem nemaj radi a tak je v systemu jen jeden. Aspon takhle jsem to onehda vygooglil, je mozny ze uz je to davno vyreseny a r8169 umi oboji HW. Ale me na nejaky trapnym AuSUSU s cipsetem SiS proste neslo. Zdenek

a problémy nepociťuju. Kdybyste měl potíže s irq, v logu by se to někde asi vyskytlo?

Kdybych věděl ... jedna diskuse pro inspiraci a ještě tady o zvukovceaneb vypsat si /proc/interrupts a přehodit kartu do jiného pci slotu, půjde-li.

Ok, tak porovnej stav při bootu z disku a z live a podle toho se zařiď, víc mne teď nenapadá.

Jaký trace? Na jméno nebo číslo?

Ok, trace = v linuxu traceroute, ve woknech tracert.
Ohledně statistiky ... k přerušením jsem zatim nic nenašel, co k síťovce: "ethtool -S eth0" ... je rozdíl mezi stavem v live a v diskové distribuci? Při diskové by tam měly být asi nějaké chyby,když "to" nejde?
