 I have built a kernel with options TRIMDEBUG and doing an rm -rf *
 in a directory containing the firefox-34.0.5.source.tar.bz (157M)
 and a directory with a second copy of it gave 45000 lines of output
 in /var/log/messages.  The last 60 lines for documentation purposes.
 Sadly I have to replace NetBSD with debian and cannot perform further
 tests, due to excessive fan noise and problems with KMS on this Lenovo
 x201 system. Some data from atactl wd0 identify:
 
 Model: takeMS SSD UTX-PO318 120GB, Rev: S8FM06.6, Serial #: F6280...
 Device type: ATA, fixed
 Capacity 120 Gbytes, 234441648 sectors, 512 bytes/sector
 Cylinders: 16383, heads: 16, sec/track: 63
 Command queue depth: 32
 ...
 TRIM supported
