nfs problem with big files

I have a laptop:
LT2: HP Compaq 6725s,
AMD Turion64 X2 Mobile 2x2GHz,
NetLink BCM5906M Fast Ethernet PCI Express, driver tg3
and 2 other computers, all with Open Suse 11.2.

when transferring big files (> 3 MB) nfs in LT2 becomes hanging:
transfer does not finish, LT2 cannot ping another, others cannot ping LT2.
sometimes, when issuing "/etc/init.d/network restart" on LT1, transfer
continues, but mostly not, I think nfs then hangs again in the rest of
the transfer.

its no difference how i do the transfer: draw with dolphin, cp ..., by
unison

when nfs hangs, in /var/log/messages about 40 lines occur, containing:
....
NETDEV WATCHDOG: eth0 (tg3): transmit queue 0 timed out
....
a call trace...
....
tg3: eth0: transmit timed out, resetting
....
tg3: eth0: Link is down.
....

Has anybody experienced such a thing?

Is this a harware error in LT2?
Or could I get a better driver for it?

thanks
Pit

1.That part makes me think that there is something faulty with the
hardware and I'd be inclinded to swap the NIC in the LT2 just to check this.

2. Next step would be to check other processes at the time, but long shop.

3. disk space?

4. what are your parameters on the nfs mount? Setting a rsize might help

host:/path1/shared /home/user/files nfs rsize=8192.wsize=8192
host:/path2/shared /home/user/images nfs rsize=8192.wsize=8192

5. do the suse boxen have permission to read it?

swap a nic in a laptop (LT2) is not so easy as i think?

that helped! in a little test.
I'll try harder the next days.

Thank you very much

I guess not. My lappies are probably ancient with NICs via pcmcia cards.
what are the modern alternatives these days?
