There is a 'TX watchdog' that will log a warning if a network device stops transmitting and the driver has not reported that the link is down. If you do not see such a warning in the log then the problem may lie outside this driver.

We'll want to see the kernel log (output from dmesg) after this happens, even if you can't spot anything in it. The device statistics (output from ethtool -S eth0) might also be informative.
