Summary: ACPI-related bug causes poor responsitivity
Product: ACPI
Version: 2.5
KernelVersion: 2.6.26.2
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Latest working kernel version: 2.6.25.2
Earliest failing kernel version: 2.6.26
Distribution: Debian
Hardware Environment: Pentium III 700, motherboard Gigabyte GA-6BX7
Software Environment: Debian Etch
Problem Description:
I noticed, that using new kernels (tested 2.6.26 and 2.6.26.2), there are
typical for ACPI-related problems troubles with responsitivity. For example:
if I'm opening "bloated" web page using Opera, one can't move the mouse
cursor smoothly around the screen; there is a "jitter" during the movement,
and any output (like GKrellm's diagrams created in real time) for that 2-3
seconds is "frozen". As I've found googling around, these are rather typical
ACPI-related problems, and indeed: forcing "acpi=off" was the cure.
Additionally I noticed, that there are no such problems while using older
kernel 2.6.25.2 - so something bad happened during the period "between"
2.6.25.2 and 2.6.26 (but I didn't try later 2.6.25.x kernels).
Following the tip of Andi Klein, I tried processor.max_cstate=1 parameter; it
made the situation a bit better - I mean: no "jitter" during mouse movement
anymore, but still "momentary freeze" of GKrellm output (which isn't the case
when using 2.6.25.2 kernel).
Steps to reproduce: by using kernel 2.6.26 in the conditions described above
