Summary: suspend is not working properly in many asus laptops
Product: ACPI
Version: 2.5
Kernel Version: 3.2-3.4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Sleep-Wake
AssignedTo: acpi_power-sleep-w...@kernel-bugs.osdl.org
ReportedBy: illumil...@gmail.com
Regression: No
In kubuntu 12.04 3.2 kernel, my asus laptop, u32u, attempting to go into
suspend will cause the screen to go off while the rest of the machine becomes
unresponsive and requires holding the power button to force it off. Ehci and
xhci drivers have to be unbinded to make the machine not lock up when
suspending.

After that, suspend will only sometimes work; sometimes it will instantly wake
from the suspend cycle. This occurs even after I have disabled everything in
/proc/acpi/wakeup. I have not been able to determine what is causing it to
wakeup, as it is random. I have tested this on the 3.4 from
http://kernel.ubuntu.com/~kernel-ppa/mainline and it still occurs randomly.
