Here is a story what happend in my PC.
My network configuration is
Router
|
|
+-+------------------+
|Corega First SWII 8P|Switching Hub
+-+-----+-------+----+
| | |
vr0 vr0 xl0
| | |
Host A Host B Host C
4.0 3.4 2.2.8
The each vr0 cards are corega FirstEtherII PCI-TX. This card
support 100/10 auto negotiation and the switching hub has also.
I check hub's lamp and each vr0 card connect with 100
full duplex mode. As well as, I check xl0 connect with 10 half duplex
mode. Of course, above 3 hosts have same netmask.
First, I copied all distribution of RELEASE-4.0 to Host B, then I
tried to boot Host A by floppies and tried to install RELEASE-4.0 via
ftp from Host B. However, after 10 or 15 bin files were transfered, the
vr0 was stalled and continuing was impossible. So, I changed
my NIC to other card (de0 shown in appendix) and continue to install.
Next, I changed my NIC to FirstEtherII again and reboot. The booting
was normal and it seemed work everything good. Then, I tried to
ftp form Host A to Host B. The login was successful and I could look
at directory and get some files. However, when I tried to get
large file, the vr0 said "unknown rx error" and network was stalled.
Whenever I tried to obtain 6M bytes files, stalling ratio was 100%. If
the file size was small, it had never stalled.
Next, I tried to ftp same file from Host C. Of course the performance
was declined, but in this case, NIC worked goods and never stalled.
I tried two more examination yesterday. First, I set ata disk mode
to PIO and tried to ftp from Host B. In this case, the NIC worked
good and never stalled.
Next, I set ata disk mode to DMA again, ftp from Host B and save it
as /dev/null. In this case, the NIC worked good and never stalled.
In conclusion, my PC's NIC is stalled when
1) using 100 Full Duplex
2) using DMA mode for ata disk
3) trying to transfer large file and write to disk at the same time.
Of course I tried to your patch. But my PC's NIC was still stalled in
above condition. At this point, I understood this problem is caused by
DMA. But I don't know where is the problem. vr0 driver? ata driver? or
my PC's chipset? Please show me suggestion if possible. I will try to
continue examination if available.
By the way, I found tiny non-fatal bug in if_vr.c
The function vr_rxeof() always prints out "unknown rx error" even if
the error is clearly. I show you quick (but not smart) patch.
After fixing, my PC says "FIFO overflow" when stalled.

if (rxstat & VR_RXSTAT_RXERR) {
ifp->if_ierrors++;
printf("vr%d: rx error: ", sc->vr_unit);
! switch(rxstat & 0x000000FF) {
case VR_RXSTAT_CRCERR:
printf("crc error\n");
break;

printf("vr%d: rx error: ", sc->vr_unit);
! switch(rxstat & 0x000000FF & ~VR_RXSTAT_RXERR) {
case VR_RXSTAT_CRCERR:
printf("crc error\n");
break;
Finally, I will show you my PC's configuration again.
