Hi! 

The thing is that I've never switched any hardware and the kernel is the same.
I didnt have these errors before.


However,

/proc/pci >>

Bus  0, device  11, function  0:
    Ethernet controller: 3Com 3C905B 100bTX (rev 48).
    Medium devsel.  IRQ 9.  Master Capable.  Latency=32.  Min Gnt=10.Max
    Lat=10.  I/O at 0x6100 [0x6101].
    Non-prefetchable 32 bit memory at 0xe0000000 [0xe0000000].

    Bus  0, device  13, function  0:
    Ethernet controller: 3Com 3C905 100bTX (rev 0).
    Medium devsel.  IRQ 10.  Master Capable.
    Latency=32.  Min Gnt=3.Max Lat=8.  I/O at 0x6200 [0x6201].
