Re: Resume from suspend-to-ram (radeon)

Hi,
I have slightly different experiances with suspend to ram and the radeon card 
on my Acer Travelmate 803 notebook:

The radeonfb resume does not crash, but when fbcon is loaded something fails. 
Compile radeonfb(original version, 2.6.4 kernel) and frame buffer console as 
modules, disable video mode selection support and load only radeonfb(NOT 
fbcon) and the system will resume with backlight on and a black screen. At 
least my device does in single user mode.

I use plain text console and X with int10 POST patch. This gives me the 
console back when resuming(X has to soft-boot the V-Bios).

i810_audio doesn't work for me too. Any call to pci_enable_device(), 
pci_write_config_byte/word/dword() and pci_restore_state() causes a 
system(bios?) lockup. This only concerns the audio card, and strangely I can 
change the pci settings with setpci and bring my card back, i810_audio unload 
of course.
I think oss has a better sound quality, especially with a high volume.

Cheers,
Stefan
