[ltp] hang when resume from Suspend-to-RAM

[Guilherme Menegon Arantes]

Hi there list,

I am having trouble when resuming from a Suspend-to-RAM.

If I suspend/resume over console, everything goes fine until I startx
when it hangs and beeps continuously around window manager startup
(after the X driver is loaded). 
If I suspend/resume over X, it resumes OK, images are fine, but as soon
as I change window/application, it hangs+beeps.
It happens either when I use a (ACPI activated) sleep.sh script (with
'echo mem > /sys/power/state' or 'echo -n 3 >/proc/acpi/sleep'), or a
hibernate + a hibernate.conf.ram
(http://linux.spiney.org/system/files?file=hibernate.conf.ram)

Disabled APIC from kernel, rmmod uhci_hcd, uhci_hcd (but not usbcore),
and it still hangs.

Same trouble when resuming from Suspend-to-Disk (done with 'echo disk >
/sys/power/state').

I am using the radeon Xorg driver (see xorg.conf bellow), vbetool, and
pass append="acpi_sleep=s3_bios" to kernel (otherwise I get a black 
screen after resume).

Anyone has the same problem? Solutions??? Tips?? 

Regards,

G
