RE: intel etherpro100 on 2.2.18p21 vs 2.2.18p17

[Allen, David B]

FWIW, I have a dual-proc SuperMicro motherboard P3DM3 with integrated
Adaptec SCSI and Intel 8255x built-in NIC.

Sometimes on a cold boot I get the "kernel: eth0: card reports no RX
buffers" that repeats, but if I follow it with a warm boot the message
doesn't appear (even on subsequent warm boots).  So this is definitely
reproducible, but it doesn't happen every time.

I can't offer much more than that, but at least you know you're not the only
one experiencing this.

We have several Supermicro 370DL3 boards (scsi, built into epro100, dual
pentium iii) - which are giving the following ethernet card error on
2.2.18p21, but not on 2.2.18p17.  This error has happened on 3 out of 4
boards with this configuration.

Oct 18 12:17:34 db1 kernel: eth0: card reports no RX buffers. 
The above message repeats itself and the ethernet card does not work.

We have the SUPER 370DL3 SuperMicro boards w/ the integrated Intel NIC,
unfortunately a warm boot does not help.  The problem also seems to happen
when I turn on the alias ip feature in the kernel under network options.

Yes, it's a problem, and it indeed happens not every time.
Dragan Stancevic has promised to check it against Intel's errata.

There is a flaw in the eepro100 driver that apparently doesnt initialise 
something properly. The problem is exasperated by the fact that the 
eepro100 driver doesn handle the buffer problem properly. We've corrected 
it by (effectively) resetting the card (by calling close and then open) 
when the first out of resources event occurs. Its not elegant, but it seems 
to work.

We have identical hardware with dual boot disks (linux and freebsd) and the 
problem only occurs with linux, and it only seems to occur with  linux. Of 
course on the DLE supermicro boards FreeBSD complains about an unsupport 
PHY, so there is no joy in mudville no matter what you do :-)

If one want to say it politely, the driver and the hardware sometimes
disagree about the initializing sequence.
Without full documentation, it's hard to say if the driver doesn't follow the
specification or it is a faulty hardware.
For example, I've never observed these problems on hardware except 82559ER.
