This entry is being used for tracking a regression from 2.6.27.  Please don't
close it until the problem is fixed in the mainline.
Comment 1 Jan Sonnek 2009-03-02 11:04:44 UTC
The bug is staill in newer kernels:
PATCHLEVEL = 6
SUBLEVEL = 29
EXTRAVERSION = -rc6-mm1

Dmesg report of the bug

It is dmesg report, when I boot new kernel 2.6.29-rc1-mm1 for example. The X windows will stop without login screen. The processor is hard working.

The linux-kernel mailing list probably won't accept a 662 kbyte email.
Please trim these reports down to some sane size.

I stared at this for a while, but my brain broke trying to work out
what lockdep is trying to tell us.

This message needs help.  A lock cannot "take" another lock.  And why
is f_lock described as "HARDIRQ-READ-irq-unsafe"?  It's a spinlock and
the "READ" part is not relevant.

kmemleak has no MAINTAINERS entry, btw.
Comment 4 Florian Mickler 2010-09-29 10:57:03 UTC
Is this still a problem?
Comment 5 Florian Mickler 2010-11-11 19:19:29 UTC
..timeout.. I'm closing this as unreproducible. 

Please reopen or comment on this bug, if you can reproduce this on newer kernels.
