Just for curiosity, do you have those messages in our logfiles:
eth0: Transmit error, Tx status register 82.
Flags; bus-master 1, dirty 20979238(6) current 20979242(10)
Transmit list 1f659290 vs. df659260.
0: @df659200 length 800005ea status 000105ea
1: @df659210 length 80000296 status 00010296
2: @df659220 length 800005ea status 000105ea
I had those with 2.4.3-pre6. They disappeared in 2.4.4. Another user
reported the same on lkml with different kernel versions.
