[issue1418] HAMMER and problem with external drive(s)

["Joel K. Pettersson \(via DragonFly issue tracker\)" <sinknull@xxxxxxxxxxxxxxxxxxxxx>]

Updating the system, that commit fixed this issue. However, when copying a
relatively large directory, I now instead encountered a second issue. This takes
longer - perhaps about a minute of copying - following which there is a panic.

If in the xorg desktop, I see during the time left until reboot occurs in the
xconsole a similar inode error message (this time with a large number as id)
followed by another hammer-related message.

Doing it on the ttyv0 console last time, up came the debugger, which had
"Stopped at hammer_btree_extract+0xf: movl 0x3c(%eax),%edx"

Thereafter (hopefully of some use):

db> trace
hammer_btree_extract(c8bfcc9c,1,ffffffff,0,c0310) at hammer_btree_extract+0xf
hammer_ip_next(c8bfcc9c,20000,80000000,18000,0) at hammer_ip_next+0x4d7
hammer_ip_delete_range(c8bfcc9c,c8c47db8,10000,0,ffffffff) at
hammer_ip_delete_range+0x22f

hammer_flusher_slave_thread(c0dfdf78,0,0,0,0) at hammer_flusher_slave_thread+0x70
lwkt_exit() at lwkt_exit
