Re: 2.6.9-rc1-bk11+ and 2.6.9-rc1-mm3,4 r8169: freeze during boot (FIX included)

Of course x86-64 has the address-space that enables >4GB RAM, and x86-64 
always supports DAC (as stated in include/asm-x86_64/pci.h), but I have 
currently only 1GB RAM, so, strictly speaking, DAC is not really necessary. 

Worse than that: r8169 in 2.6.9-rc[1/2] does not advertise its ability to
DMA to high memory. 

Strange enough, the latest Realtek driver 2.2 does not even support DAC (only 
the lower 32 bit of the DMA-Addresses are written to the registers).
Could it be that the Realtek driver does not support DAC for a good reason?

Anyway, I will continue searching for the problem...

Can you simply try the attached patch with the network cable unplugged ?

It will not fix your issue but if the result & 0x08 != 0, you can probably
stop your testing for now as it will mean "known issue".
