When ACPI.PSD is loaded (and it doesn't matter which switches is used) PCI config space gets destroyed for some devices - in my case my Wlan Intel 3945abg. This have been happening even in all 2.x versions too.

Since more and more users reports similar problems for other devices, I tried to compare, and it seems that this problem only happens for devices connected to PCI Express bus.

In my case it happens to 3945 device connected to PCI-e and the PCI-e root port.

Other users report the same problem happens to their Gigabit nics - when this is connected to PCI-e too.

It seems, there is some general problem with ACPI driver about PCI-e devices, as I have not seen any case where a normal PCI device gets its PCI config space destroyed by ACPI driver.

Plenty of logs uploaded during time - but I'd be happy to supply more, if needed (there are a few in Ticket #226, which shows some of them).

Reimplementing PCIWRITE is a nice tool for experts and hardcore users to test and workaround this problem; but we _really_ need to figure out, what goes wrong here, and fix that.

HP Tablet notebook tc4200.

When booting it hangs, usually at screen01.sys - sometimes a few drivers l8r. Tried almost all switches without luck; but when using /FS it sometimes boot all way.

Logs provided for such a boot. PC has no serial port to capture all the bad boots.

ASUS A8N SLI Premium AMD 3800X2 NForce 4 chipset Award 6.0PG BIOS 3GB RAM.

System can now boot for first time in full SMP mode. However, it takes 30-50 secs to load all BASEDEVs, measured from BM to ACPI banner. Rest of config.sys loads normally. In /PIC or /VW mode (or without PSD) same takes 7-8 secs.
