Not a regression from 2.6.26.

Comment 3 Rafael J. Wysocki 2008-09-21 15:08:48 UTC

Do you mean that commit 664d080c41463570b95717b5ad86e79dc1be0877 was present in 2.6.26?

Comment 4 Zhang Rui 2008-09-21 19:33:48 UTC

Shaohua has a patch set which fixed a lot of dock issue.
please give them a try. :)

note that there are 11 patches in all.

BTW: seems like a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=451399

Comment 5 Michal Vaner 2008-09-23 12:33:52 UTC

I got a all-in-one patch by mail from Holger Macht (the author of the changes is Shaohua), so it should be the same patchset.

It fixes the issue, removing and inserting of the device work and the interrupts disappeared.

Should I test these patches too, or is this OK?

Thank you

then, you don't need to test these patches. :)

Mark this bug as PATCH_ALREADY_AVAILABLE.
