Summary: Boot slowdown/timeout (2.6.27 regression)
Product: ACPI
Version: 2.5
KernelVersion: 2.6.27
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: EC
AssignedTo: acpi...@kernel-bugs.osdl.org
ReportedBy: robin.bankh...@gmail.com
Latest working kernel version: 2.6.26.8
Earliest failing kernel version: 2.6.27.*
Distribution: Gentoo
Hardware Environment: x86 (Celeron Northwood 2.6GHz on Toshiba A30-104 laptop)
Software Environment: gcc-4.3.2, glibc-2.8_p20080602-r0
Problem Description:
Gentoo kernel maintainers have asked me to kick this upstream. It is a
regression that is fixed in 2.6.28 but they (and I) would like to get it fixed
in 2.6.27 tree.
Starting from 2.6.27, the kernel starts to boot normally,
then just around the time init begins, output slows to a crawl and may hang
altogether. This persists right through init and during the KDE4 desktop
session, and causes various errors on login, e.g. "the process for the
desktop:/ protocol died unexpectedly".
Speed can be regained by keyboard activity, e.g. holding down the ALT key.
Touchpad responsiveness times out frequently, but can be temporarily restored
by using the keyboard.
The bug does not occur when I boot with acpi=off.
In the console, typing is as responsive as normal, but console-output programs
like powertop are very slow.
CPU fan activity remains constant, even when the system is idle and CPU
activity is low according to top and powertop.
To follow: dmesg output from 2.6.27.8 (bad) and 2.6.28-rc2 (good). Please let
me know if you require any further info, and see also:
