Same thing has happened to me when I connect with smbclient to
our NT-server(3.51 USSP 4) , when transferring stuff from at full speed
linux goes completely stuck in 30 seconds or so.

but ftp works well between machines.

Ethernet card is SMC etherpower PCI and driver is that DE500 driver.

In different kernel versions seem to have no difference (now it is 1.3.97)
