Re: dsched_fq and occasional console freeze

:I wonder if this:

:
:is related, I did enable DSCHED_FQ via sysctl just before I ran "hammer
:cleanup" I remember now, and the symptoms are same - freeze but can switch
:between terminals, but can't actually execute any command because they are
:all "hanging", for about 5 minutes and eventually freeze completely but
:without a kernel dump.

    I think it might be.  A bug in DSCHED_FQ could cause the I/O to not
    get properly completed and stall the NFS server.
