Public bug reported:
If an SD-Card is mounted suspend (to RAM or to Disk) causes a System-Crash on
Ubuntu 10.04 LTS.
This problem will be found in older Versions of Ubuntu too. People who are
Using Netbooks with an SSD are facing it mostly, because they use SD-cards to
store user-data.
I added the following Script to handle the Problem:
---
#!/bin/sh
# File: /etc/pm/sleep.d/10_umount_sd
# This script fixes issius with sleep or suspend when a SD-card is mounted.
case "${1}" in
hibernate|suspend)
/bin/sync
# Find all SD/MMC-Devices
for drive in $( /bin/ls /dev/mmcblk?p* ); do
# Unmount each device
/bin/umount ${drive} > /dev/null
# If failed: abort suspend
if [ $? -ne 0 ]; then
# If the device really keeps mounted
/bin/mount | /bin/grep ${drive}
if [ $? -eq 0 ]; then
exit 1;
fi
fi
done
;;
resume|thaw)
# Mount all devices mentiond in /etc/fstab
mount -a > /dev/null
done
;;
esac
