8139too bug in 2.4.4 (2.4.3?) & VIA 686a

[Ignacio Monge <ignaciomonge@navegalia.com>]

	Hi, here I again with another problem :)
	Since I have installed kenel 2.4.3 & 2.4.4 (nothing went wrong with
default kernel in MDK 8, 2.4.3mdk), my ethernet card is not recognized
correctly.

	This is my ifconfig output:
eth0      Link encap:Ethernet  HWaddr 00:E0:29:9A:CB:62  
          inet addr:192.168.0.1  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:437 errors:0 dropped:0 overruns:0 frame:0
          TX packets:302 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          RX bytes:70770 (69.1 Kb)  TX bytes:222559 (217.3 Kb)
          Interrupt:11 Base address:0xc000 

	The HWaddr is correctly (I'm using 2.4.3mdk actually). But, with
2.4.3-2.4.4 this value is incorrect, and after a couple of minutes, kernel
displays a message like this "Clock timer bug, may be a hardware bug VIA
686a." After reboot linux, this BIOS setup has deleted (CMOS checksum
error...), and the default values reloaded.

	I can't use another kernel than 2.4.3mdk.

	I hope this may help.
