Hi Guys,

I have several 3Com 3c905C-TX Fast Etherlink XL NIC's but they work
very bad with 7.0 and 6.2. The problem appears when I have more than
50 Mb through the network interface. Then the card restarts maybe the
driver restart it I am not sure.

dmesg shows me something like:

xl0: transmission error: 90
xl0: tx underrun, increasing tx start threshold to 120 bytes
xl0: link state changed to DOWN
xl0: link state changed to UP
xl0: link state changed to DOWN
xl0: link state changed to UP
xl0: link state changed to DOWN
xl0: link state changed to UP
xl0: link state changed to DOWN
xl0: link state changed to UP
xl0: watchdog timeout
xl0: link state changed to DOWN
xl0: link state changed to UP


What do you think maybe this NIC is buggy or I have to change something?

dmesg -
xl0: <3Com 3c905C-TX Fast Etherlink XL> port 0xec00-0xec7f mem 0xe7000000-0xe700
007f irq 10 at device 12.0 on pci0

uname -a -

P.S. I've seen the same with all my cards and xl driver.


Thanks in advance
