 Hello,
 I've got some problems during dumping ( with /sbin/dump ) my
 filesystems to SCSI 8mm tape drive. Here is my HW/SW config:
 
 	HW: 	HP Vectra N2 4/66 486 DX2 machine
 		32MB RAM
 		AHA-1540CF/1542CF with BIOS v2.01 SCSI adapter
 		1 GB IBM DPES-31080 S31K SCSI disk
 		EXABYTE EXB-8500SMBANXH1 0458 8mm SCSI tape drive
 		WD SMC Ultra eth. card
 
 	SW:	FreeBSD 2.1.0-RELEASE
 
 	When dumping filesystems to tape drive with:
 	
 	/sbin/dump 0ubdf 32 105000 /dev/nrst0 /dev/sd0s2g       <-- /home
 
 OS hangs up with these err. messages on system console:
 
 	aha0: MBO 02 and not 00 (free)
 	sd0(aha0:0:0): timed out
 	adapter not taking command.. frozen?!
 	Debugger ("aha1540") called
 		AGAIN
 
 and dump utility writing these error messages:
 	
 	DUMP: Date of this level 0 dump: date is here
 	DUMP; ....
 	DUMP: Dumping /dev/rsd0s2g (/home) to /dev/rst0
 	DUMP: mapping (Pass I) [regular files]
 	DUMP: mapping (Pass II) [ directories]
 	DUMP: estimated xxxxxxx tape blocks on 0,xx tape(s)
 	DUMP: dumping (Pass III) [directories]
 	DUMP: read error from /dev/rsd0s2g: Input/output error: \
 	[sector 36592]: count=2048
 
 After these messages i'm forced to use HW reset to reboot system.
 Any suggestions would be most appreciated
 
 				Thanks, miro
