Oops & ata link gone after resume from suspend

[Bug Report]

Just had this almost crash...

The system freezes / oopses / looses ata link after resume from suspend with natty daily live.

The first time it happened I was in Xorg terminal vt7 - nuveau driver loaded. After no response for ~20 seconds I rebooted with alt-sysrq-b.

The second time I tried from console vt1 and - maybe - waited a bit longer until a kernel message appeared on the console. I realized it must be a kernel oops, changed to vt7 where apport was waiting...

[Bug Report (bugreport-mailinator)]

Subsequent tries to suspend the machine failing -- probably because of this...

[Bug Report (bugreport-mailinator)]

This bug is reproducible

[Bug Report (bugreport-mailinator)]

Installed natty with mini.iso ("net-install")
System up to date now.
Suspend/Resume works.
Done

[Bug Report (bugreport-mailinator)]

The laptop sill doesn't resume reliably. It works ~40% of times only. I "accidently" managed to take this kernel oops screnshot recently. I showed up on an external monitor. At other times, when I try to resume, the screen just stays black with a blinking cursor top-left....

[Bug Report (bugreport-mailinator)]

When I think about it, I realize these must be 2 seperate bugs. First it was suspend problems, now it's hibernate - suspend is actually working now
