Comment 1 Chuck Ebbert 2011-06-27 05:52:38 UTC 
fs/ext3/inode.c:1571:
        WARN_ON_ONCE(IS_RDONLY(inode));
Comment 2 Eric Sandeen 2011-06-27 15:28:48 UTC 
Couple things:

> Tainted: G        W

 10: 'W' if a warning has previously been issued by the kernel.

So you got a warning before this.  Do you know what it was?


>         WARN_ON_ONCE(IS_RDONLY(inode));

so it's tryin to write back an inode on a filesystem marked readonly:

#define IS_RDONLY(inode) ((inode)->i_sb->s_flags & MS_RDONLY)

Did the fs hit an error and go readonly prior to this?
Comment 3 Dave Jones 2011-06-27 16:04:02 UTC 
It's worth noting that virtualbox was loaded. we're seeing a lot of fs/io related bugs with that loaded lately.  It might be that it's causing latent bugs to show in ways that bare-metal isn't, but I'm more inclined to believe it's part of the problem based on what we've seen so far.
Comment 4 Josh Boyer 2011-09-26 18:15:17 UTC 
Can you recreate this on the latest F15 kernel without the vbox modules loaded?
Comment 5 Dave Jones 2011-10-06 22:11:17 UTC 
pretty sure this is vbox, given all the other similar bugs we've seen the last few months.
Comment 6 Frank Mehnert 2011-10-12 09:29:54 UTC 
Changing both things (VirtualBox modules and Fedora) at the same time will not give us any evidence.

Which version of VirtualBox did you have installed at the time this bug was triggered? Can you still reproduce it? If so, also without the VirtualBox modules loaded?
