Summary: Shutdown hangs after acpi_power_off called only if
sounds outputed before.
Product: ACPI
Version: 2.5
KernelVersion: 2.6.22.4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Off
AssignedTo: acpi_power-off at kernel-bugs.osdl.org
ReportedBy: s3321037 at ncnu.edu.tw
Most recent kernel where this bug did not occur: 2.6.13.5
Distribution: Debian etch
Hardware Environment:
CPU: P4 3.0GHz
MB: Gigabyte GA-8I915P Pro (Rev 1.x) North: i915P, South: ICH6.
VGA: Leadtek WinFast PX6600 TD PCI-E (NVIDIA GeForce 6600)
NIC: Broadcom 5751
SND: C-Media 9880 CODEC (UAJ) (driver: snd_hda_intel)
Software Environment: Xorg 7.1.0, GNOME 2.14.3.6
Problem Description: Shutdown hangs after acpi_power_off called only if sounds
outputed before. No matter whether X/GNOME runs or not, if no sounds output
from my speaker until shutdown, things will be fine.
The problem is similar to bug 6431 but I have no sky2 drive installed.
Steps to reproduce:
1. cat something.wav > /dev/dsp
2. shutdown -h now
3. acpi_power_off called (power isn't off.)
