Hello kernel developers,

I do have two problems with running Linux on my Sony Vaio PCG-FX501 Laptop.

1.) When I do a reboot, the bootup logo (a nice animation from Sony :-) 
displays, and the HD light turns on and stays on forever. Approximately 30 
seconds later, the logo goes away, and I do see the Phoenix BIOS' startup 
screen, saying

ERROR
0211: Keyboard Error

I do have the option to use <F2> to enter Setup, but due to some strange 0211 
keyboard error it just won't work. The only proper way for restarting my 
machine is to power it off and turn it on again.

What can I do?

2.) The laptop seems to put itself to sleep when I don't do anything for a 
longer period of time. The display becomes black (the backlight is still on, 
though) and I can't do anything except powering off and on again to make the 
machine work again. No messages about anything interesting are in my syslog 
files after this has happened. The problem persists both with ACPI and APM.

The only thing that fixes this problem is loading or installing the sonypi 
driver into the kernel. It doesn't function as expected, but it solves at 
least *this* problem. (As documented in the driver, sonypi should be able to 
set/get the backlight intensity of the display, but that doesn't work. There 
are even more features that it has but that are non-operational on my 
system.)

This is all okay, especially as I can now leave my laptop alone for even more 
than 10 minutes or so without having the need to turn it off and on again 
afterwards. OTOH, with sonypi my via82cxxx_audio driver won't work. 

When compiled into kernel, I see the follwing message:

Via 686a audio driver 1.9.1
PCI: Assigned IRQ 5 for device 00:07.5
PCI: Unable to reserve I/O region #1:100@1000 for device 00:07.5
Trying to free nonexistent resource <00001000-000010ff>
Trying to free nonexistent resource <00001c54-00001c57>
Trying to free nonexistent resource <00001c50-00001c53>

PCI dev 00:07.5 is the AC97 sound controller (lspci output):

00:07.5 Multimedia audio controller: VIA Technologies, Inc. AC97 Audio 
Controller (rev 50)

In my /proc/ioports, I do see that the two devices have intersecting I/O 
ranges:

1000-10ff : VIA Technologies, Inc. AC97 Audio Controller
  1080-109f : Sony Programable I/O Device

I dunno much about kernel or PCI internals but I guess that this is the 
problem for the "Unable to reserve I/O region message - tell me if I am 
wrong. I also have found a pci_request_region() call inside the 
via82cxxx_audio driver but I don't know how to modify that call so it does 
only request the I/O regions that do not mix with sonypi's range - and of 
course, I don't know if this would be good, but as the two devices co-exist 
nicely and my sound is working as long as sonypi is neither modprobed nor 
compiled in, I suspect it to work as soon as I can pci_request_region() only 
those I/O portions that are still free. So if someone could tell me how to do 
this (just in case no one states "Will break your kernel forever" or "Won't 
even work after that") I'd try it on my machine. I could even try to create a 
patch from it (it would be my first patch to an already existing piece of 
software... :-) and post it here - I am very interested in doing some work to 
make Linux better for tomorrow.

So, just for completeness, here's my system configuration:

Mobile AMD Duron Processor, 1GHz
256MB RAM
IDE hard disk and CD/DVD ROM

sonypi driver startup message:

sonypi: Sony Programmable I/O Controller Driver v1.10.
sonypi: detected type2 model, camera = off, compat = off
sonypi: enabled at irq=11, port1=0x1080, port2=0x1084
