This entry is being used for tracking a regression from 2.6.38. Please don't
close it until the problem is fixed in the mainline.
It was suggested to enable CONFIG_TREE_RCU, but this did not help:

Then it was suspected that it could be an old hrtimer bug and a patch was proposed, but it did not help either:
This issue is still present in 2.6.39-rc5-00091-gfafc992.
Dave Chinner posted a patch that helps, it's not in mainline (yet):
Thanks for the update.
Fixed by commit 228d62dd3f74734b9801c789b5addc57fdfc208f .
