Hi All,

I tried to suspend the system, and got the following messages:

PM: Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.00 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.00 seconds) done.
Suspending console(s) (use no_console_suspend to debug)
musb_bus_suspend 2261: trying to suspend as a_host while active
pm_op(): usb_dev_suspend+0x0/0x8 returns -16
PM: Device usb1 failed to suspend: error -16
PM: Some devices failed to suspend
Restarting tasks ... Segmentation fault
done.

I use linux-omap-2.6.git, should I use the branch linux-omap-pm? Thanks.
