Here's an update.  I tried the new kernel, and I seem to be having some
new (possibly worse problems.  In my ssh session, I'm seeing many errors
of this sort:

Message from syslogd@guru at Jan 26 13:13:14 ...
 kernel:[  308.223834] BUG: soft lockup - CPU#0 stuck for 23s!

 kernel:[  308.248754] BUG: soft lockup - CPU#2 stuck for 23s!
 [btrfs-delalloc-:594]

In the logs, I'm seeing several warnings and bugs, including:

WARNING: at fs/btrfs/extent_map.c:78 free_extent_map+0x79/0x90 [btrfs]()
WARNING: at lib/list_debug.c:62 __list_del_entry+0x82/0xd0()
