Looking at the 88e8056 PCI config values:
Differences:
1. Linux use MSI (no INTx), Vista does not.
2. Vista use IRQ 16, Linux uses 219 (because of MSI)
3. Vista sets Device Control(E8) 4000h = 2K,
Linux uses 2000h = 1k
This would cause larger max read requests.
4. Vista status (EA) 0010h
Linux is 0019h
Driver doesn't bother clearing the correctable error status on boot.
You can get the same settings on Linux without changing driver by doing:
modprobe sky2 disable_msi=1
setpci -s 04:00 e8.w=4000,19
No luck, I tried it, but it still dies..
