Description Paulo Roma Cavalcanti 2003-06-13 08:17:11 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Linux 2.4.20-18.7 i686) Opera 6.12  [en]

Description of problem:
Hardware: dell inspiron 7500 - 512 Mb ram
Kernel: 2.4.20-18.7

RedHat has changeg  kernel configuration since 2.9 series.

Suspended mode of several laptop brands stopped working since then.

The problem is in .config of the source kernel.

CONFIG_APM_CPU_IDLE=y  <----------------------  wrong

should be like 2.9 kernel series: 

# CONFIG_APM_CPU_IDLE is not set

This has little impact, and solves all of the troubles of apm freezing when returning
from suspended mode.

Every time I want to update to a new redhat kernel I have to recompile it to have apm working again.

Please consider my request and change the configuration of new kernels.
This problem does not only occur with inspiron laptops, but with a lot of different brands,
which can be easily checked on the net.

Thank you.


Version-Release number of selected component (if applicable):
X freezes after suspended mode

How reproducible:
Sometimes

Steps to Reproduce:
1.Suspend laptop
2.
3.
   

Actual Results:  Generally freezes when returning from suspended mode.

Expected Results:  Should work always, the way it was in 2.9 series and below.

Additional info:

I have tested the cited modification in kernel 2.4.20 (either standard or redhat's)
and works perfectly.

Comment 1 Arjan van de Ven 2003-06-13 08:20:44 UTC
you don't need to recompile for that;
apm=idle_threshold=100
on the kernel commandline has the same effect.
If you can send me the dmidecode output of your machine I can even make this the
default for this laptop. (dmidecode is part of kernel-utils)

thanks; I've added your bios/machine to the list of "don't do apm idle" machines.
