Description Florian Mickler 2011-02-15 22:05:47 UTC
This entry is used to track the second(?) issue of bug #28642. It should be closed when the issue is fixed in the mainline kernel.

Comment 4 Rafael J. Wysocki 2011-02-19 13:45:27 UTC
Hmm.  That may be fixed in the current Linus' tree, by patches that went in
after -rc5.
Comment 5 Adam Kovari 2011-02-20 11:10:30 UTC
This does not happen with vfat drive. It is not fixed in -rc5.
Comment 6 Rafael J. Wysocki 2011-02-20 11:29:15 UTC
Well, clearly FUSE is involved then.  Reassigning.
Comment 7 Rafael J. Wysocki 2011-02-20 11:31:09 UTC
It still would be good to verify if -rc6 still has the problem, when it's out,
there have been a few fixes in the VFS area merged since -rc5.
Comment 8 Cristian Aravena Romero 2011-02-20 22:49:31 UTC
See: bug #29492 , It is not fixed in -rc5
Comment 9 Adam Kovari 2011-02-23 17:40:18 UTC
It is not fixed in -rc6.
