When I suspend (s2ram) my Acer 8930 laptop under both Ubuntu 10.4 and
12.4 same problem appears (and also on fedora). Laptop can hibernate
(s2disk) well, but suspend (s2ram) is not working. After suspend it
freezes on wakeup and when I press Ctrl+Alt+F1 this text is being
periodically printed out:

[4480.58016] ata1: irq_stat 0x00000040, connection status changed
[4505.402689] ata1: SError {DevExch}

[4523.58053] ata1: irq_stat 0x00000040, connection status changed
[4521.415321] ata1: SError {DevExch}

[4535.58853] ata2: irq_stat 0x00000040, connection status changed
[4585.458621] ata2: SError {DevExch}
...

and so on, only the number in Square brackets [] changes.

I tried to install uswsusp and hibernate packages from synaptic but no change,,
I also tried most of options of s2ram with no success. Windows suspends ok. 

** Changed in: linux (Ubuntu)
       Status: Confirmed => New
