Any FreeBSD machine with KingByte USB Pen Drive (http://www.kingbyte.com/products/pendrive.htm) installed.

FreeBSD daal.astralblue.net 4.3-STABLE FreeBSD 4.3-STABLE #2: Wed Aug  8 05:58:25 KST 2001     root@daal.astralblue.net:/home/root/build/usr/obj/usr/src/sys/PL-DAAL-4  i386
>Description:
Any program that tries to read/write data from/to KingByte Pen Drives will hang in a non-killable state.  This is because Pen Drives, like some other flash-based drives, don't support 6-byte SCSI READ commands.
>How-To-Repeat:
Access the Pen Drive using programs like dd(1) as in: dd if=/dev/da0 of=/dev/null count=1
>Fix:
Add the following quirk entry to src/sys/cam/scsi/scsi_da.c:

	{
		/*
		 * KingByte Pen Drives
		 * do not support READ_6 commands, only READ_10. 
		 */
		{T_DIRECT, SIP_MEDIA_REMOVABLE, "NO BRAND", "PEN DRIVE", "*"},
		/*quirks*/ DA_Q_NO_6_BYTE|DA_Q_NO_SYNC_CACHE
	},
