Hello Gentooers!

I am expieriencing some issues with Suspend/Resume (no matter if RAM or disk).
After resuming, There seems to be a kernel bug:

Afterwards, My USB soundcard does not work anymore (USB mouse works fine).

An additional but probably unrelated issues is related to my wireless card. It
gets disconnected after resume:

wlan0: authenticate with AP 00:1c:4a:1f:a1:b1
wlan0: RX authentication from 00:1c:4a:1f:a1:b1 (alg=0 transaction=2 status=0)

wlan0: associated
wlan0: CTS protection enabled (BSSID=00:1c:4a:1f:a1:b1)
wlan0: deauthenticate(reason=3)

I am using gentoo-sources-2.6.26-r1. Full dmesg, kernel config and
emerge --info can be found here: http://big.homeftp.net/~pholthau/

Any help would be very much appreciated.

What hardware are you using? Is it a laptop or desktop pc?

Few general suggestions:
1. update your bios to latest version.
2. Try to load motherboard-specific acpi module (e.g. asus-acpi for asus notebooks, or acer-acpi, or ...)

I's a Dell Inspiron 9400.

I think there isn't any for dell. Correct me if I am wrong, cause I'm not at
the laptop right now.

I suspend happily with a Dell Inspiron 9100, but I think the 9400 is
different enough to worry about...

I noticed nvidia in that list. Can you suspend without it? Try booting
without loading the nvidia module at all (sometimes even just loading
and unlaoding the nvidia module can cause issues with suspending). Also
stop as many services as possible and unload as many modules as possible.


Then when it works, you can add modules one by one and keep testing the
suspend / resume behaviour.

<carpaski> I'm greatly disturbed by my process list saying that a
process started 3 minutes from now.
<spyderous> carpaski: it's the latest in kernel scheduling. it can
actually plan ahead to see where resources should go.
