So, as I just mentioned I bought a Compaq Evo N160 notebook a few days ago
and I installed Mandrake 8.2 on it. It's been working nicely, most things
have just worked out of the box. The one thing I'm having issues with is
ACPI. Now, it doesn't *do* APM as far as I know, so ACPI is pretty
important. Here's what I've tried.
Enabling ACPI in both the 2.4.18-6mdk and 2.4.18-21mdk kernels and
recompiling. 2.4.18-6mdk wouldn't build (broken ACPI patch I guess),
2.4.18-21mdk built, and after loading the modules I got the appropriate
entries in proc, but it's too old a patch for the software I've been trying
to use it with and it says helpful things like I don't have a battery. It
can inform me of when the machine is plugged in though, so that's a start.
I then tried to patch the 2.4.18-21mdk source with the current version of
the acpi code - version 20020726, unsurprisingly it failed since Mandrake
had already patched the kernel with the old ACPI version.
So, then I downloaded a clean, non-mandrake-tainted kernel and tried to
patch that. The config file was copied from the previous kernel version (the
mandrake one), and I ran through and made precious few changes (if any, I
don't quite remember), got the kernel built eventually (well, I've mucked
around with it through about 10 builds now). Anyway, everytime I boot one of
these ACPIed kernels I'm getting a message that says:
Unknown bridge resource 2: Assuming transparent.
and then the machine just stops (that messages was from memory, I'm pretty
sure that's what it is, but it could be slightly different).
I really don't know how to fix it. Has anyone got any ideas or had
experience with similar problems they can share?
What's the most recent version of ACPI that people have running on Compaq
Notebooks? Do I need a kernel patch for it to know about the bridges in the
machine? The PCI bridge currntly shows as an unknown intel in lscpi.
Let me know if there's anything else you need to know.
Many thanks,
James.
