Bug#711585: [linux-image-3.9-1-loongson-2f] linux 3.9.4-1 for loongson-2f doesn't halt/reboot/suspend-disk.
Package: linux-image-3.9-1-loongson-2f
Version: 3.9.4-1
Severity: Important
When rebooting, halting or suspending to disk on a mini-pc with
loongson-2f, it just hangs, printing a weird trace.
Fortunately dmessage kept such trace:

Currently reverted to:
linux-image-3.2.0-4-loongson-2f
3.2.41-2
This is important cause unattended servers will hang upon reboot/halt...
Thanks,
