Could the delay not be the cause, but a side effect ?
Yes, that's probable. It might be possible that some interrupt got delayed too much, or that packets were completed in wrong order.
I've noticed that using the touchpad triggers the issues, even in console mode when I don't start X. Some other factors seem to trigger it, like some graphical operations or hard disk usage (but again, only when the CPU is low usage).
I forgot to mention that my integrated soundcard does not have this issue. I deactivated the integrated soundcard in the BIOS and that didn't help.
Do you have any idea why keeping my CPU busy removes the problem ?
I'd guess that an idle CPU needs a longer time to wake up. What CPU and what CPU frequency governor are you using?
On my laptop, I've got an Atom Z520 @ 1.33GHz. I was using the ondemand governor. I switched to performance, with no effect.
I tried to disable as many modules as possible (even my graphics card, wifi, touchscreen) with no luck so far.
I tried again on several of my other computers and I could not reproduce the problem, even on another netbook. It's quite weird becaues I thought I reproduced it with several hardware back in December, but I guess I was mistaken, sorry about that.
