I've just bought a Dell Inspiron 1420N laptop (which came with Ubuntu 7.04 installed, but which I've since replaced with Fedora 7). I've worked out most of the kinks, but there's one which is a little frustrating:
After waking up from hibernating, the sound card stops working. Killing all the processes using it, removing the soundcard driver and re-modprobe-ing it fixes it, but it's a pain having to do that every time.
I was wondering if anyone else had found this, and if so if there was a way to fix it? Or if not, if anyone knew a little more than I do about the mechanics of the hibernate/resume process and how to cure quirks like that.
A little device info:
