patch to disable acpi cleanly on load failure (1.77 KB, patch)

Add an attachment (proposed patch, testcase, etc.)

Description Alex Galakhov 2003-07-26 09:26:14 UTC 
Distribution: Debian sid unofficial/unstable + kernel 2.6.0-test1 from kernel.org source 
Hardware Environment: Tyan Thunder II motherboard, 2xP2 CPUs 
Software Environment: See distribution 
Problem Description: The /proc/acpi directory does not exist. ACPI stuff that's usually in 
/proc/acpi is placed directly in /proc and seems to be not working (these directories are 
empty). All the ACPI stuff is compiled into the kernel (not modules). ACPI reports warnings 
about ACPI tables while booting. 
 
Steps to reproduce: Just boot the system and look at /proc/ after it is mounted.

can you attach the DSDT and ESDT.
Comment 2 Len Brown 2003-11-12 18:17:44 UTC 
does this still happen with a recent kernel? 
 
thanks,

patch to disable acpi cleanly on load failure

please test this patch on your system.	It should disable acpi on the failure
and so there
should be no acpi entries left hanging around in /proc.

Of course it may be an additional bug that ACPI doesn't load on this system...
