Subject: Need pci=assign-busses for Acer Aspire 9410

Hi,

dmesg on my Acer Aspire 9411 AWSMi says:

> PCI: Bus #0b (-#0e) is hidden behind transparent bridge #0a (-#0a) (try
> 'pci=assign-busses')
> Please report the result to linux-kernel to fix this permanently

The computer seems to work well with and without pci=assign-busses.  (I 
had to pass combined_mode=libata as kernel option, for otherwise DMA does 
not work and the hard disk is terribly slow.)

I'm attaching dmesg output, without and with pci=assign-busses.  Please 
ask me by e-mail if you need more informations.

         Eric
