This entry is being used for tracking a regression from 2.6.31.  Please don't
close it until the problem is fixed in the mainline.
Comment 1 Theodore Tso 2009-10-03 22:40:22 UTC 
The problem has gone away in the latest release.  Linus posited that commit ID 89133f935 might fix the problem, and while I haven't tested to make sure that it is indeed the commit that made the problem go away, a kernel built using 2.6.32-rc1-git4 is no longer exhibiting the problem, and it was drop-dead easy to reproduce before.

Linus seems to be a little dubious about original bisected commit (75c5158f) and whether it should be reverted entirely, but for now, the problem seems to be fixed.
