Description of problem: The following message from a kernel 2.6.13-1.1560_FC5 on x86_64 showed up when I was shutting down an extra X-server: idr_remove called for id=5 which is not allocated. Call Trace:<ffffffff8020110b>{idr_remove+255} <ffffffff8024de9b>{release_dev+1920} <ffffffff8016a13e>{free_block+443} <ffffffff801673ca>{dbg_redzone1+28} <ffffffff80167e96>{cache_free_debugcheck+516} <ffffffff801675b0>{poison_obj+49} <ffffffff8024dece>{tty_release+17} <ffffffff80186875>{__fput+188} <ffffffff80183f06>{filp_close+90} <ffffffff801367c3>{put_files_struct+117} <ffffffff8013781e>{do_exit+532} <ffffffff80138305>{sys_exit_group+0} <ffffffff8010daec>{tracesys+209} Apart of this "which is not allocated" and a traceback so far this does not seem to have any further consequences. I also failed to reproduce that.
repeatable with current rawhide ?
> repeatable with current rawhide ? Well, I got it with a relatively current one. :-) As I wrote I could not reproduce that even with a setup where this showed up. If this is some race then that I cannot repeat it does not mean that much.
Ok, there's no other reports of this, and that code did change somewhat since 2.6.13, so I'm going to close this. Feel free to reopen/file a new bug if it reoccurs.
