Ubuntu 8.10 with all upgrades.
Laptop Lenovo Ideapad Y530
During suspend to disk the screen switches to text mode with text
similar to:
NOHZ: local_softirq_pending 100
ata1: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4
ata1: irq_stat 0x00400040, connection status changed
ata2: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4
ata2: irq_stat 0x00400040, connection status changed
Then nothing happens and the laptop remains powered-up.
After manual power-down and reboot the system correctly and nicely wakes up
from the hibernation.
Therefore, the hibernation can be achieved, but not in the right way.
On the same machine suspend to RAM results in a blank screen in a text
mode. After manual power-down and restart the system does not wake up,
but the usual reboot happens. Therefore, suspend to RAM does not work.
