Hi,

we are running an embedded system here based on the PXA300 platform.
Suspend/resume used to work well so far. However after upgrading the
kernel from 2.6.34.7 to 2.6.35.6, we get the following error when trying
to suspend the system:

# echo "mem" > "/sys/power/state"
[ 5647.295953] PM: Syncing filesystems ... done.
[ 5647.318792] Freezing user space processes ... (elapsed 0.01 seconds) done.
[ 5647.337048] Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
[ 5647.356915] Suspending console(s) (use no_console_suspend to debug)
[ 5647.366651] pm_op(): platform_pm_suspend+0x0/0x5c returns -38
[ 5647.366671] PM: Device pxa2xx-mci.0 failed to suspend: error -38
[ 5647.367082] PM: Some devices failed to suspend

Regards,
