| |
I have a Dell Inspiron e1405 laptop with a Core 2 Duo processor. Under every 64-bit kernel I have tried yet, it hangs when I close the lid (or, I would assume, do anything else that activates System Management Mode). It works fine under 32-bit mode; closing the lid turns the LCD off using DPMS.
I understand that this might be entirely outside the control of the kernel developers, but I would of course love to be able to use this laptop in 64-bit mode. What information would be needed to fix it, and/or how would I go about debugging it? I've tried turning the console loglevel up to 9, but no information is printed right before the crash (probably since an exception occurs in SMM, and isn't caught?). I think booting with noacpi (I'm not sure, I'll check) made it work, but disabled all the power management features, making the rest of the laptop much less useful.
Thanks in advance,
