Hi folks,
I've been an unhappy HP Compaq 6715b owner for more than a year now. Tried lots of distros, currently using Ubuntu. I'm almost satisied, only have one big problem: my system only boots if I pass the acpi=off option to the kernel.
(To be more precise, when ACPI is enabled, disk read/write speed is about 200kB/s, therefore the boot process takes about 20 minutes without loading window manager.)
Now this is unacceptable as most likely you need CPU frequency scaling and suspend support on laptops, right?
Interesting fact: I've managed to get ACPI working on Gentoo linux before. Only on 64-bit though. 64-bit Ubuntu does not work, nor do any other distros. With acpi=off everything works perfectly.
I also tried to compile a custom kernel for Ubuntu - tried to include everything I could remember I included in the Gentoo kernel config, but no luck: with ACPI enabled, I get this freaky message when loading the kernel:
Code:
Module 'acpi' failed to be added to sysfs, error number -17
The system will be unstable now.
Please tell me what information you need to help me, I really need to get this working. Using Windows is not an option!
Thanks in advance!
