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.
Andi, does it still happen with the current mainline?
This problem appears to have been fixed in current mainline. Closing.
Rafael, I meet the same problem on 2.6.27-rc7 when testing cpu hotplug on a 4 core SMP machine,
then I go through the history of mainline, find one commit (2133b5d7)which looks like to be related to this bug, but its content is adding a debugging feature on classic RCU, not a bug fix, so do you know in which commit i could find out the solution, thanks.
