At the time of tx timeout, the registers all return 0xffffffff.  Does
the subsequent reset bring the device back?  If the device is brought
back, there should be a link up message and traffic should resume.  If
not, please provide lspci -vvvxxx on the eth0 device after the failure.

Also, when one ethernet port fails, does the other port (from the same
dual port device) function ok?

Thanks.
