Dual-Ethernet DECchip 21142/43 doesn't like cold boots

[Michael Hunold]

Hi,

I have a dual-ethernet DECchip 21142/43 based card in my system. The 
problem is, that the device doesn't work after a cold boot.

After I have powered up my system, the syslog shows the following 
message and the device doesn't work.

-----------------------------schnipp------------------------------------

A simple shutdown and warm boot gives the desired result:

Any other warm reboots works as well.

"lspci -v" says the following about this card:

-----------------------------schnipp------------------------------------

The same problem exists with 2.4.26 w/o ACPI. As you can imagine it's 
quite annoying to restart the system once everytime after a cold startup.

Is anyone interested in this bug report? All comments or hints 
appreciated, because I haven't worked with the Linux network code up to 
now. 8-)

Interesting - I'm occasionally seeing same warnings with SMC EtherPower II.
May be unrelated, though. And despite the warning, the card actually
works.
This is SMC epic100 chip, not a Tulip or clone.
