Regression in dock/ata driver

Hi folks,

I'm here to report a regression in the dock or ata driver. I found the old thread where me and another affected user are discussing the bug: http://kerneltrap.org/mailarchive/linux-kernel/2008/9/1/3152964/thread
The bug was eventually fixed and my laptop worked fine for a while. Now I'm seeing the bug again.

The patch in this thread looks related:
http://kerneltrap.org/mailarchive/linux-kernel/2008/6/1/1996064/thread
I will test if commit 246dd412d31e4f5de1d43aa6422a325b785f36e4 or IOW v2.6.26-rc4-212-g246dd41 (which is the merge commit right after the patch from the thread was merged into linux-2.6) still has the bug and report back.

Attached is my current config for 2.6.28-rc8 (which is what I'm running right now).

I'd hate to bisect it, because you folks tend to change the kernel config often and then 'make oldconfig' asks lots of questions and I can't be sure that the new kernel will boot. So if you have an idea where the problem might me or even have a patch ready that I could test, that would be great.

There's is also http://bugzilla.kernel.org/show_bug.cgi?id=11703, which seems to be heavily related. I think it's actually the same issue, just that in this bug, there's only the bay drive which gets removed, not the whole docking station (which shouldn't matter for libata's resume functions).

I'll try to get my hands on a system where I can reproduce this to be able to do sensible debuggin.
