Subject: Suspend to RAM broken on BeagleBoard ?
Date: Fri, 10 Sep 2010 17:48:14 +0200 [thread overview]
Message-ID: <20100910174814.6e5d439e@surf> (raw)
Hello,
I've tested the current linux-omap Git tree and Kevin's pm-core branch
on a BeagleBoard using the omap3_defconfig, and when trying a suspend
to RAM, I get a "Class driver suspend failed for cpu0" :
# echo mem > /sys/power/state
[ 93.395050] PM: Syncing filesystems ... done.
[ 93.410827] Freezing user space processes ... (elapsed 0.01 seconds) done.
[ 93.434570] Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
[ 93.458557] Suspending console(s) (use no_console_suspend to debug)
[ 93.590728] PM: suspend of devices complete after 119.629 msecs
[ 93.593902] PM: late suspend of devices complete after 3.112 msecs
[ 93.594421] Class driver suspend failed for cpu0
[ 93.595153] PM: early resume of devices complete after 0.518 msecs
[ 93.887603] PM: resume of devices complete after 292.052 msecs
[ 93.922851] Restarting tasks ... done.
Is this a known issue ?
I also have a problem with USB support, both on linux-omap and Kevin's
pm-core branch. My USB Ethernet adapter, supported by the asix driver,
isn't detected anymore. With a pm git tree of a couple of weeks ago, it
was working. This is again with just a plain omap3_defconfig.
Thanks!
Thomas
