Things are like this: I use "udisks --mount /dev/sda3" to mount "data" which is a ntfs filesystem. similarly, I use "udisks --mount /dev/wd5000bpvt/big" to mount "big" which is a ext4 filesystem. After finish using these filesystems, I use "sudo umount /media/data /media/big" to umount the filesystems, and the hole system just suddenly halt (mouse is not moving). using alt-sysrq-b to reboot the system. nothing record in the /var/log/messages. So, How could I record the kernel error/info, when system was halt ?
