realtek bug: rtl8139.c v1.23 and RTL8139D chip

hello donald becker

i have nearly the same problems like [email protected].
my kernel version is 2.4.4. i use a network card from www.claxan.com
equiped with a RTL8139D chip. i have downloaded the 
netdrivers-3.4-package from your site and successfully installed
it on my linux-box. the card is not sharing any interrupt with some
other device.

if i transmit larger files by ftp, the network apapter
seems to stop working. i always get an "Abnormal interrupt, status 
00000021.". pinging to another host does not work any more. pinging
to myself via my ip or 127.0.0.1 still does work.
there are no other abnormal interrupts except the one with status
00000021. the abnormal interrupt activated by pulling out the
ethernet cable and inserting it again is managed correctly, but does
not recover "Abnormal interrupt, status 00000021." only unloading the
network-drivers or bringing the interface down and again up solves
the problem.
how is it possiple to create a status RxOK (0x01) and RxUnderrun (0x20)
simultaneously?

thanx
eRiC
