It's either a post-2.6.33 or a post-2.6.34 regression.

In 2.6.35 rcs, I get frequent freezes of my computer when I put a DVD (its a DL DVD-Video, if matters) in for playback. I do not know how to get any data out of the computer in this situation, nothing works (not even the caps lock). So I turn it off and restart to use it again.
2.6.33 kernels do not have this problem and I have not tried .34 yet as those kernels have a nasty acpi bug on my computer
(https://bugzilla.kernel.org/show_bug.cgi?id=16040).

It would be helpful to test 2.6.34. There are fixes referenced in that report but they aren't present in 2.6.34.1. I suspect a screwup and will ping Len about that.

Could someone instruct me how to debug this please?
From your dmesg:

ata6: SATA link down (SStatus 0 SControl 300)
ata2: SATA link down (SStatus 0 SControl 300)

so we can perhaps start by asking the ata developers to take a look, please.

Len, the patches in https://bugzilla.kernel.org/show_bug.cgi?id=16040
don't appear to have made it into 2.6.34.1, even though they were written a month earlier. This 2.6.34 regression is preventing at least one tester from testing 2.6.34.x kernels for a different regression.

Did we forget to backport those fixes into -stable?

Thanks.

No, we didn't. I sent -stable requests to stable & Greg several days ago.
