>Originator:     Dirk Meyer
>Release:        FreeBSD 2.2.5-RELEASE i386
>Organization:
privat
>Environment:

	Adaptec 1542C SCSI-Controller
	SCSI-Tape "HP HP35480A 1109" type 1 removable SCSI 2

>Description:

	The SCSI-Tape caused the SCSI-Controller to freeze
	if sync-negotiation for this device is not disabled.

	After reboot and fsck I lost all the files touched
	in the last 30 minutes. All these files have been
	closed for at least 10 minute. on a syncornus mounted
	ufs file-system. 2 other partitions on the
	same disk are asyncronously mounted without any
	inconsitency on them (e.G. /tmp ).

>How-To-Repeat:

	This Problem is reproduceable, even if i press reset
	on an idle machine.

>Fix:

	workaround:
	add folowing line in /etc/crontab

	*       *       *       *       *       root    /bin/sync
