Hi Andrey,

I've been using an older EEPro100/B card until now and it's been working without any
problems ever since the transmitter bugs were fixed. The boot output looked like this:

eepro100.c:v1.09j-t 9/29/99 Donald Becker http://cesdis.gsfc.nasa.gov/linux/drivers/eepro100.html
eepro100.c: $Revision: 1.35 $ 2000/11/17 Modified by Andrey V. Savochkin <saw@saw.sw.com.sg> and others
eth0: Intel Corporation 82557 [Ethernet Pro 100], 00:A0:C9:41:F4:DE, IRQ 9.
  Board assembly 667280-003, Physical connectors present: RJ45
  Primary interface chip i82555 PHY #1.
  General self-test: passed.
  Serial sub-system self-test: passed.
  Internal registers self-test: passed.
  ROM checksum self-test: passed (0x49caa8d6).
  Receiver lock-up workaround activated.       

Intel webpage says: 667280-xxx is a model EEPro100/B but I dunno which chipset.


Today I've installed a new model with Wake-on-LAN support and got caught by
above mentioned

eth0: card reports no RX buffers.
eth0: card reports no resources.

messages as well. Strangely those messages only ever happen during bootup and
*every* time. Shutting eth0 down and bringing it back up fixes the problem.

What puzzles me a bit is that the newer card (721383-xxx) is an 82559 chip,
according to the Intel site, but the boot output doesn't say so:

eepro100.c: $Revision: 1.35 $ 2000/11/17 Modified by Andrey V. Savochkin <saw@saw.sw.com.sg> and others
eth0: Intel Corporation 82557 [Ethernet Pro 100], 00:02:B3:1F:BA:5D, IRQ 9.
  Receiver lock-up bug exists -- enabling work-around.
  Board assembly 721383-016, Physical connectors present: RJ45
  Primary interface chip i82555 PHY #1.
  General self-test: passed.
  Serial sub-system self-test: passed.
  Internal registers self-test: passed.
  ROM checksum self-test: passed (0x04f4518b).  

If you have any patches or tests that would help to find and fix this init
bug, I'd offer to test them out, since I can reliably reproduce the problem.

Regards,
Udo.
