The cam_sim_free() is stuck, blocking the rest of that controller from

Apparently sim->refcount > 0.
Not sure how to check who has the reference(s).
Can anyone think of something I can try?
To recap to save you going back through history -
After running 9.0 - 9.2 for 3 years I upgraded to 10.1RC3 and started
getting a locking issue, most new processes fail to start, top and ps
failing being indicators, the most info I have got is a back trace
using kgdb, there are 4 instances I got output from procstat -kk -a
On several occasions I have found that after inserting a usb memstick
the device failed to be created, leaving me unable to mount the
filesystem without a restart.
I then switched to stable/10 in hopes of a fix finding it's way in.
The back traces I have been able to collect (and a dmesg) are listed at
http://shaneware.biz/freebsddebugdata/
This is my everyday desktop machine. I am now running
FreeBSD leader.local 10.1-STABLE FreeBSD 10.1-STABLE #11 r283839: Thu
Jun 4 17:41:28 ACST 2015 root@leader.local:/usr/obj/usr/src/sys
/GENERIC amd64
I can only say it appears to be getting worse, though I may just be
getting sick of having to restart nearly every day. Lately it seems that
the less I do the quicker it locks up. I have restarted twice this week
and then let it sit while I have gone out, after returning I get maybe
10-15 mins then have to restart, one of them was less than an hour uptime.
While running poudriere I have got past 1 day uptime but it locks up
harder and I don't usually get a chance to record any data.
Hi,
One solution is to use fuse instead of the native fs, until the CAM/SCSI
refcount issues are resolved.
