HI, FYI - this patch did fix my initial issue, but further work in multi-user mode caused it to still hang. I haven't diagnosed it yet; I just put back the yield call so bufdaemon could run.
So yeah, we still have some work to do. It hit the same problem; stuck in a loop calling the path to wakeup bufdaemon, but then not sleeping on anything. -adrian On 2 November 2015 at 14:13, Adrian Chadd <adrian.ch...@gmail.com> wrote: > Hi Tijl, and others; > > Here's something that Jeff came up with that fixes my problem: > > adrian@victoria:~/work/freebsd/head-embedded/src % svn diff sys/kern/ > Index: sys/kern/vfs_bio.c > =================================================================== > --- sys/kern/vfs_bio.c (revision 290048) > +++ sys/kern/vfs_bio.c (working copy) > @@ -2910,7 +2910,7 @@ > } while(buf_scan(false) == 0); > > if (reserved) > - bufspace_release(maxsize); > + atomic_subtract_long(&bufspace, maxsize); > if (bp != NULL) { > bp->b_flags |= B_INVAL; > brelse(bp); > > > Would you/others please try this and see if it improves things?
