I'm working with a FreeBSD 8.1-RELEASE/amd64 machine that's attempting to write data to an ordinary Kingston 8 GB microSD card. The card has been inserted into its USB adapter and plugged into a USB port on the machine. The system is locking up repeatedly with messages that say (da1:umass-sim1:1:0:0): SYNCHRONIZE CACHE(10). CDB: 35 0 0 0 0 0 0 0 0 0 (da1:umass-sim1:1:0:0): SCSI sense: Error code 0x52 A Web search reveals that problems like this have cropped up for many, many FreeBSD users as far back as 4.x. But I can't seem to find any solution (which amazes me; if there's a bug, one would think it would have gotten some attention). Do I have to abandon the use of FreeBSD with USB thumb drives (or maybe with USB altogether)? Hope not, but I may have to if I can't get this fixed. --Brett Glass
