Description cam 2004-05-29 20:46:48 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8a2)

Description of problem:
There is a kernel patch to:

To change the OS name passed to the ACPI code
#define ACPI_OS_NAME                "Linux"

The patch changes the name to "Microsoft Windows XP" because that is
detected by many BIOSes.

Adopting this change would improve the compatability of the kernel
with laptops / notebooks. The upstream ACPI code will probably have
this change.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. use a recent binary kernel

Actual Results:  see unreliable ACPI behaviour

Expected Results:  proper ACPI behaviour

Additional info:

A workaround is to pass the acpi_os_name="Microsoft Windows XP" at
boot time

Interesting idea; I'll try it for a few builds to see how it goes
Comment 2 Arjan van de Ven 2004-06-09 06:01:29 EDT
