Hang at resume with AC adapter not plugged

Hang at resume with AC adapter not plugged

Hi everybody,

I have a little problem with software suspend 2.1.9.1[012] on 2.6.13-rc[3456]. 
The system hangs on resume if the AC adapter is not plugged in. Everything 
works well if I use 2.1.9.5 on 2.6.12.x or plug in the AC adapter. I've tried 
acpi-20050729 for 2.6.13-rc6 but that did not change anything. The system is 
a Sumsung X10.

Any ideas what could be the problem?

Do you have the ACPI modules compiled in, or built as modules? I'd
suggest that you try building them as modules and unloading while
suspending if you're not doing that already.

Sometimes (very seldom) it also hangs if the AC adapter is plugged in, so I 
tested some more and found another interesting fact: It boots just fine if I 
use splash=verbose insted of splash=silent (even without AC adapter). I've 
patched the kernel with fbsplash-0.9.2-r4-2.6.13-rc[16].

Any idea what could be the cause?
