Problem Description:
The system is unable to wake up after suspend to ram.
The suspend process works fine.
But when I push the power button, It's impossible to get a functional system,
there is a lot of lines like these:
ata1: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
ata1: SError: { DevExch }
ata2: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
ata2: irq_stat 0x00000040, connection status changed
ata2: SError: { DevExch }
The only way to reboot is with SysRq keys.
A complete bug has been posted in launchpad at:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/301353
Using /etc/acpi/sleep.sh or s2ram is identical.
I don't know if it's a problem with acpi bios or a kernel bug.
