This entry is being used for tracking a regression from 2.6.26.  Please don't
close it until the problem is fixed in the mainline.
Comment 1 Dmitry Torokhov 2008-08-20 06:04:22 UTC 
Is it reproducible in 2.6.27-rc3? Or is it only in Ingo's tree?
Comment 2 Rafael J. Wysocki 2008-10-24 14:31:18 UTC 
Ingo, I guess it's been fixed already?

no, AFAICS it's an input layer locking problem and i've seen no fixes 
for this specific bug.
