Just to follow up on the really obvious, this failure is in fsync(), at:
error = VOP_FSYNC(vp, fp->f_cred,
(vp->v_mount->mnt_flag & MNT_ASYNC) ? MNT_NOWAIT : MNT_WAIT, p);
where 0x40 is MNT_ASYNC, and %eax is supposed to contain vp->v_mount, but
contains a NULL pointer instead. Since this is filesystem related, I should
mention that I have both MFS and PROCFS in the kernel, and that MFS is
mounted on /tmp (async, local). (if this makes any difference)
