[Bug 485108] Re: [IBM 1834RTG] late resume failure

[grigaman]

I have the same issue on my Sony VGN-FW11ER with kernel from Ubuntu
karmic repository. But in my case I can make suspend to work (but lost
brightness in this case). I install kernel image from mainline (At
present I use 2.6.31.6 version). In this case brightness doesn't work
(there no device in /sys/class/backlight/), but if I patch DSDT table,
brightness starts working,  /sys/class/backlight/ has device, but
suspend do not want to resume - laptop completely hangs. So I think the
problem is situated in kernel - acpi. What else my test shown that in
kernel 2.6.29 brightness and suspend worked, in 2.6.30 suspend with
brightness did not want to work.
