Do you have the resources to run a before/after test of the LTP on amd64 and i386? This is mostly to make sure the MD -> MI move does not cause regressions.

Are you running -current? If yes I Looks try to get some time to commit the linuxulator-dtrace probes, now that SDT probes can be loaded dynamically there is no risk to panic the system when the linuxulator is loaded after boot and dtrace is used. This could help looking at problems with locks.

With a slow system and a slow line this may take a while. I hope to at least update my branch in SVN (users/netchild/linuxulator-dtrace) today. I don't know if I get the time to merge it to HEAD today.

linuxulator dtrace probes
Hi, can someone please test a little bit http://www.leidinger.net/FreeBSD/current-patches/linuxulator-dtrace-20120414.diff on amd64 and i386? Reviews are welcome too. With this you get some static dtrace probes in the linuxulator and some dtrace scripts which check for various things in the linuxulator. You need to run a linux program to test them, off course. You need to have at least r233552, else you may experience a panic if you have loaded the linux module after booting and want to do something with dtrace (even if it is just listing the probes). The diff is relative to /usr/src/sys.

I think I changed the locking-probes since I gave the patch to you, but I'm not sure. Anyway, the patch against a recent -current is available from http://www.leidinger.net/FreeBSD/current-patches now.
