Description Byron Miller 2001-08-10 23:46:19 UTC

Description of problem:
When using roswell on a DELL C600 i come across a problem that after
resuming from an apm monitor shutdown within a few minutes the whole pc
freezes and i have to hard shutdown.  By default the 2.4.6 kernel doesn't
recognize the acpi system on this laptop so it defaults to apm for
powermanagement (which is also enabled under kde to monitor battery juice)

I manually compiled 2.4.7 with ACPI and ACPI management so apm doesn't load
and i don't have this problem anymore. (kernel module, bug in 2.4.6 or??)

is there a later kernel i can load from redhat or just stick with my custom
one?

How reproducible:
Always

Steps to Reproduce:
1.boot into xfree86
2.let apm shutdown monitor
3.use for a few minutes,
4. letp apm kick in
5. pc freezes
	

Actual Results:  lockup - looks like verything is normnal, but no response
from keyboard, mouse or pointing devices (touchpad, usb mouse and keyboard)

Expected Results:  resume from apm

Additional info:

dell c600
p3 1000mhz
256 megs ram

We (Red Hat) should really try to fix this before next release.

I've been working on resume problems on a Dell inspiron 8000 recently (a
coworker has one) and fixed several things in the resume code in the kernel.
Once kernel 2.4.7-2.4 or later enters Rawhide, could you try with that ?

Comment 3 Byron Miller 2001-08-17 14:37:28 UTC
I am downloading rawhide right now. I will give it a shot and keep both releases
on my laptop to see how it works.

One question, with the new ACPI power management features in 2.4.7 or higher
kernels should i even bothere with APMD?  It looks like the new ACPI stuff works
with the cpu temp, monitor disable, spin down, spin up and all that good stuff

ACPI is currently disabled, and will be for quite some time. The reason for that
is that ACPI executes bios code in kernelmode (and lots of it) and most bioses
have SO many bugs in it that it's unworkable.

Comment 6 Arjan van de Ven 2001-08-17 14:40:22 UTC
Oh and I'm not sure -2.4 is in rawhide yet; iirc -2.0 is in there; rawhide is
only updated once a week or so and I fixed this yesterday
