But if it doesn't help for you, you have some other issue (which is not
surprising - yours wasn't a SETFXSR error, and I don't think it would have
worked very well before either).

So since it apparently _did_ work for you before, can you bisect it?

git bisect told me that this is the first bad commit:
commit d4b2bab4f26345ea1803feb23ea92fbe3f6b77bc

libata: add deadline support to prereset and reset methods

I suspected my unstable timing source and booted with acpi=off. Now
the printk timestamps are in sequence but the bug is still there.

The drive worked flawlessly with the old ide-cd. So what's the
difference between libata and ide-cd?

Is there a kernel parameter to completely disable probing the cdrom?

Thanks,
Gregor
