Hi!
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
Modify 64bit kernel entry point to do something trivial (flashing
character on vga text mode?) then see if lid close breaks it. If so,
blame smm, and force vendor to fix it.
I have the same problem, kinda sorta. Closing the lid causes it to go to
sleep in the context that a vetrinarian uses. ("It was put to sleep.")
Wakeup just spins the drive. And spins. And spins. And spins.
The machine is also a 64bit. HP zv5200z AMD64 3700+.
According to a friend, 32bit suspend works in 32 bit but not 64bit.
