The following panic was seen during system shutdown, still I've seen a similar panic during normal operation as well. Unfortunately, I have only a single crash dump saved.

panic: solaris assert: dsl_prop_unregister(ds, "atime", atime_changed_cb, zfsvfs) == 0, file: /usr/src/sys/modules/zfs/../../cddl/contrib/opensolaris/
cpuid = 0

 I'm seeing this problem almost every day, mainly during system shutdown.
 
 The box is a home router/NAS/BitTorrent client. I'm turning it on
 early in the morning, and shutdown late in the evening, so the average
 uptime is approx. 14-18 hours. The BitTorrent client (Transmission) is
 quite active (seeding about 200GB of quite popular content with
 outgoing speed of 512Kbit/s), so there must be a lots of random reads
 from disks during the day. The system uses a single ZFS pool with two
 1TB SATA disks (mirror). The pool and all the file systems it has have
 been recently upgraded from previous version.
 
 If any additional information is required, please ask me.
 
 Andrey.

 Hi,
     Can you upgrade to 9.x and please try and reproduce the issue
 again? It might have been resolved via ZFS v28. If the issue persists,
 please drop me a line so I can setup a debug session with you and we
 can further isolate the issue.
 Thanks,
 -Garrett

 Hello Garret,
 
 I have updated the affected system to 8-STABLE about a week ago, and
 the problem seems to disappear. I have not upgraded the pool yet,
 though. I am going to see how it works for another week or two and
 will then upgrade the pool.
 
 Regards,
 Andriy.

Hi, 

I've upgraded the pool to v28 and all underlying filesystems to v5 two 
weeks ago. No problems so far. I think you can close the PR as 
resolved in v28. 

Thanks and best regards, 
Andriy.
