After
quite a lot of playing with pm-suspend quirks, I've managed to figure out that
Xen does not wake up from suspend correctly on my HP Compaq 6510b.
I
am running Ubuntu 8.04 with Xen-3.2.1.
I've
tried suspending from console, VESA X and accelerated X (Intel Mobile
GM965/GL960 Integrated).
When
Xen is not running, suspending from X works correctly (There are a few issues
such as that the backlight does not turn on when using VESA), while from
console it does not (for some strange reason).
When
I restore the computer from sleep state with Xen, the fan starts working, but the
computer freezes completely and no devices return from sleep (such as wifi).
I've
also tried playing with Xen's acpi_sleep boot option (s3_mode, s3_bios) and no
combination of the flags works.
I was
able to suspend Xen once correctly with the command "pm-suspend" with
no arguments, but I am not able to reproduce this.
Does
anyone have any idea why this happens?
