Hi,
I'm in the process of upgrading machines from R.13.5 to 14.3
So far I have been hit by multiple issues of troublesome behaviour:
1.
Installing security/ca_root_nss takes 65 seconds instead of formerly 10 seconds.
I noticed this on the build engine, where it is done quite often to install the proper port dependencies.
This is reproducible and happens on all concerned machines.
2.
Early boot often stalls for an arbitrary time at different lines.
The worst I have seen was a stall at "Launching APs:" that required 56 minutes of CPU time (consumed by the bhyve process).
This is not reproducible (and not always that extreme) and happens only slightly on metal, mostly on guest.
3.
One of my rc.d scripts used to take 22 seconds on 13.5, now it takes 245 seconds!
This is reproducible. the immediate cause is clearly the OS upgrade, root cause might be something else. Will look into that after I can properly boot.
4.
Boot hangs after setting hostid, and does not proceed.
I tracked this into /etc/rc.d/zpool, which invokes
When trying to import the pools manually, it also does hang at about every 10th invocation (there are 16 pools). It isn't on a CPU, just locked up in "D" (everything else disk-related will then also hang).
