Bug#656062: pm-utils: pm-suspend does not enter suspend and hangs system on Asus U35JC

[David Banks]

Package: pm-utils
Version: 1.4.1-8
Severity: normal

On an Asus U35JC, using pm-suspend does not cause the laptop to enter a
suspended state. The system drops to the console with a blinking cursor, but
that's all. The system fans continue to spin, as if CPU activity were high, and
all relevant LEDs remain as before. Attempting to resume does nothing, and the
system is totally hung.

In order to get suspend to work I had to use the following script in
/etc/pm/sleep.d, found at at <http://robbyx.net/blog/?p=190>:

#!/bin/sh

BUSES="0000:00:1a.0 0000:00:1d.0"

case "${1}" in
hibernate|suspend)
# Switch USB buses off
for bus in $BUSES; do
echo -n $bus | tee /sys/bus/pci/drivers/ehci_hcd/unbind
done
;;
resume|thaw)
# Switch USB buses back on
for bus in $BUSES; do
echo -n $bus | tee /sys/bus/pci/drivers/ehci_hcd/bind
done
;;
esac

The hardcoded $BUSES worked for my hardware. I don't know if this is really a
bug, or if it should be reported against this package or the kernel package, but
maybe this information will help someone. For the record, pm-hibernate had the
same issue that it would not shut down the system, but when booting up again
after hard poweroff it would resume from hibernation without any problem.

Cheers,
David

Thanks. Let's call it a kernel bug, even though it's more likely a BIOS
bug.

What kernel, BIOS version, etc do you use? Please attach output from
"reportbug --template linux-image-$(uname -r)".

Thanks,
Jonathan
