* interrupts (i use irqbalance, but problem was the same without)

I wonder if you tried without SMP too?

No i did not. Do you think that this can be a problem ?
To test with no SMP, do i need to recompile kernel or is there a kernel parameter ?

It's always better to exclude any complications if it's possible.
Yes, there is the kernel parameter for this: nosmp. So, if you
have some time to spare I think 2.6.23-rc2 with this nosmp
could be an interesting option.

BTW, Jean-Baptiste and Chuck - it seems, unless you have too much
time, there is no use for testing my "genirq: fix simple and fasteoi
irq handlers" patch.

Well i just  tested 2.6.23-rc1 with your patch and copied (using smbclient) big files :

Aug  7 11:11:53 loki kernel: NETDEV WATCHDOG: eth2: transmit timed out
Aug  7 11:11:53 loki kernel: eth2: transmit timed out, tx_status 00 status e601.
