Comment 8 for bug 674984

I have just tried the Natty B1. Apart from the fact that the touchpad right button get stuck, here you are the results for standby/hibernate.

From The liveCD:
==========
Suspend to disk (hybernate): not available
Suspend to RAM (standby): works
Resume: does not work
Messages on console:

SQUASHFS error: unable to read fragment cache entry [xxxxxxxx]
SQUASHFS error: unable to read page, block xxxxxxxx, size xxxxxx
SQUASHFS error: unable to read data cache entry [xxxxxxxx]

Installed on a USB disk:
===============
Suspend to disk (hybernate): seems to work as it dumps data on the disk before shutting off the machine.

It is possible that the BIOS does not allow resume from external drives.

Suspend to RAM (standby): works
Resume: does not work
Messages on console:

EXT4-fs error (device sdb1): ext4_find_entry:933: inode #2: comm unity-panel-ser:reading directory lblock 0
EXT4-fs (sdb1): previous I/O error to superblock detected

This is the same behaviour as with 10.10 booted with the noapic kernel parameter, basically it is like if the USB bus does not get properly awakened.

Note that whit this notebook the BIOS triggers automatically hibernation (suspend to disk) after the notebook has been suspended to RAM for a while. This seems to be by design and independent from the OS. With windows it is the same.
