If I'm running poudriere on my desktop (i7-5930k) I'll frequently get I/O errors when doing (an unrelated) installkernel to a laptop over wired ethernet.


root@planecrash:/home/mmacy/devel/fbg-merge # time make -j12 installkernel -s
--------------------------------------------------------------
>>> Installing kernel GENERIC
--------------------------------------------------------------
find: /mnt/storage/mmacy/devel/fbg-merge/sys/modules/netgraph/pred1: Input/output error
make[2]: "/mnt/storage/mmacy/devel/fbg-merge/sys/conf/kern.pre.mk" line 196: warning: "find /mnt/storage/mmacy/devel/fbg-merge/sys/ -name \*_if.m" returned non-zero status

and then later on the install fails with:
===> ispfw/isp_1080 (install)
install: radeon_hainan_me_bin.ko.debug: Input/output error
--- _kmodinstall ---
*** [_kmodinstall] Error code 71

At which time I saw the following on the console:

Jul 10 18:04:11 planecrash kernel: newnfs: server '10.0.1.20' error: fileid changed. fsid 0:0: expected fileid 0x4, got 0x2. (BROKEN NFS SERVER OR MIDDLEWARE)


This problem has existed for at least as long as I've been working on graphics.

Add the "-S" command line option to mountd. Poudriere
mounts file systems and this triggers a reload of /etc/exports.

Please let us know if this fixes the problem.
(If it fixes the problem, I will mark this as a duplicate of
 the others.)
