This smells like a hardware failure.  The PCMCIA drivers are writing
0x68000000 to a register, and it is reading back as 0x680000dc.  Maybe
Windows works because it only writes to this register and never relies
on reading it back.

Just for kicks, you could try editing modules/i82365.c, find the line
that says:

 pci_readl(s, PCI_BASE_ADDRESS_0, &s->cb_phys);

and add right after that:

 s->cb_phys &= ~0x0fff;

Agree looks like you're right

Great suggestion! When we meet the beer is on me.

By hard-wiring i82365.c I'm now back online. I went for the full-bore hardcoded memory address:

s->cb_phys = 0x68000000;


PS. I'm also seeing the dropped ethernet interrupts after a suspend/resume. I'm not a driver programmer but if you need someone to guinea pig some new code on a N505VE please give me a shout.
