Default Suspend/Resume Inspiron 1464/1764 Lucid bug# 571422

Mario/Jerone,

I trying to help Ben (cced) with suspend resume issues he is seeing on
Lucid with his Inspiron 1464 & 1764 models. He has done some preliminary
debug, he says "testing all modes in /sys/power/pm_test succeed, but when
I echo none to it, the system does not come back. According to the
documentation, this suggests that it is in the invocation of the platform
firmware"

Buglink: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/571422

Can you guys pls advice as to what the next steps are in figuring out what
the issue/fix might be ?

Cheers

Default Suspend/Resume Inspiron 1464/1764 Lucid bug# 571422

Hey guys,
This is could be the same issue we have seen on other Dell machines
(and some other vendors). Where the SCI_EN bit isn't being set .. try
this kernel here:
http://people.canonical.com/~achiang/lp-532374_566149/

Add kernel command line:
acpi_sleep=sci_force_enable

Let me know what happens ?

Jerone

I tested against the 2.6.34 upstream kernel, with that command line flag
set, and it seemed to resolve the issue.

...now to try to get it working with my Xen patch set...
