Issue #3187 has been updated by t_dfbsd.

File dmesg.boot added
File fstab added

Adding some machine info:

Samsung 1TB SSD containing:

- encrypted root

Data drives:
- 10TB SATA encrypted primary
- 8TB SATA encrypted backup (hammer-mirrored PFSes from primary drive)

Bug #3187: Kernel: multiple swap pager messages during hammer cleanup
http://bugs.dragonflybsd.org/issues/3187#change-13779

* Author: t_dfbsd
* Status: New
* Priority: High
* Assignee: 
* Category: 
* Target version: 
----------------------------------------
On master, commit a19800f223, running hammer cleanup causes dozens of messages like this and causes the machine to become inaccessible by network services, SSH in particular, although ping still works:

May 23 19:20:14 <kern.crit> boojum kernel: swap_pager: indefinite wait buffer:  bp 0xfffff800735334d8 offset: 5092941824, size: 4096  m=0xfffff8005fee7580 busy=e0000000 flags=00004080

This behavior was also observed at commit d29a2431b3, so whatever is causing it is probably earlier than that. When I ran hammer cleanup today, the last thing I noticed running before my SSH connection died was hammer reblock-btree. This was on a 8TB encrypted volume.
