problem s RTL8111/8168B

caw ludia, mam problem s touto sietovou kartou na ubuntu (2.6.22-14-generic). Robi to asi tolko ze vsetko ide ok pokial nestahujem nejake vacsie subory, ked zacnem stahovat nieco vacsie tak mi odpoji eth0 akoby sa zhodil ovladac..... v ifconfig -a to vypise

eth0      Link encap:Ethernet  HWaddr 00:18:F3:C6:F5:03  
          inet addr:147.175.186.10  Bcast:147.175.186.255  Mask:255.255.255.0

          Interrupt:20 Base address:0x4000 

a na nejaky cas som odpojeny od netu, ked dam

ifconfig eth0 down

vypise

no device 

alebo nieco podobne...
po nejakom case sa ti spravi (priblizne 1 min) , alebo ked odoberiem modul r8169 a znova ho natiahnem tak to znova ide.... skusal som to aj s driverom od realteku r8168 bolo to to iste....

tu je daky log :
