So, I found the problem, I reported the bug 3 weeks ago. I told that the NE-PCI probing hangs on my RTL8029AS nic. It hangs on the end of the first pio_write call in the probing. Dirk von Suchodoletz told me, that with the old 4.4.x version this probing runs ok. So I did a code comparison and found one significant difference in the ns8390.c #ifdef INCLUDE_NS8390 eth_flags |= FLAG_16BIT; /* force 16-bit mode */ #endif Thew problem is that the probing code 'defines' that the card has to do data transfers in 16bit mode and pio_write and pio_read depends their operation to this flag. But 'nobody' tells the chip, that it 'must' use 16bit mode. I removed the code (#if 0..#endif), and the etherboot for my card works well. Why was this line added in version 4.6. Are there cards which needs this data transfer mode in this state of initialisation ? The problem with the Rtl8139 I have not debugged yet.
