-------- Original Message -------- Subject: Suspend to RAM broken on BeagleBoard ? From: Thomas Petazzoni <thomas.petazzoni@xxxxxxxxxxxxxxxxxx> Date: Fri, September 10, 2010 11:48 am To: "linux-omap@xxxxxxxxxxxxxxx" <linux-omap@xxxxxxxxxxxxxxx> 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!
