[realtek] Frequent timeouts.

[Rogier Wolff.]

Hi,

Since a few days we're getting frequent timeouts on a few of our 
RTL8139 equipped machines. 

Jun 21 15:54:20 cave kernel: eth0: Transmit timeout, status 0d 0000 media
00.
Jun 21 15:54:20 cave kernel: eth0: Tx queue start entry 9694  dirty entry
9694.
Jun 21 15:54:20 cave kernel: eth0:  Tx descriptor 0 is 8010a042.
Jun 21 15:54:20 cave kernel: eth0:  Tx descriptor 1 is 8010a042.
Jun 21 15:54:20 cave kernel: eth0:  Tx descriptor 2 is 8010a042. (queue
head)
Jun 21 15:54:20 cave kernel: eth0:  Tx descriptor 3 is 8010a042.

0000 05e1 40a1 0001 0000.

Jun 21 14:22:54 assurancetourix kernel: NETDEV WATCHDOG: eth0: transmit

Cave runs 2.2.14pre1 (Yes, that's old.)
assurancertourix runs 2.4.0-test1-ac18 .

Are we running a version of the driver that's too old? Is this a known
problem? Workarounds?

Oh, on cave I've had to ifconfig down/ifconfig up the interface a bunch
of times to get things going again. Usually that's not neccesary though.
