Summary: acpi is enabled but there is no /proc/acpi
Kernel Version: 2.6.16.14
Status: NEW
Severity: normal
Owner: [EMAIL PROTECTED]
Submitter: [EMAIL PROTECTED]
Most recent kernel where this bug did not occur: unknown
Distribution: Gentoo
Hardware Environment: MSI ms-7191 (ati rs482m4 with sb450) athlon64-3200+
Software Environment:
Problem Description: /proc/acpi does not exist, even though acpi is enabled.
This could be related to the buggy DSDT of this board. There is a 0x03
character in a ACPI name (as reported in dmesg below).
Steps to reproduce: boot with noapic. (Without noapic I cannot boot if acpi is
enabled in my BIOS.)
output of "dmesg|grep -i acpi":
