Summary
-------
System freezes when writing large amount of data to external buffer drive.


Full Description
----------------
I was created 4 large files on an externally mounted Hard Drive.  Doing 
this using the dd command.  Each file is roughly about 600MB or so.  After 
doing this for a while, the system just hangs and doesn't do anything 
else.  I can't access the drive or do an 'ls' on them either.  The light 
on the drives is constany lit as well, which never happens unless error.


Kernel Version
--------------
We are using verions 2.4.19


Output
------
The only output would be to whatever comes out from what we're running.  
We don't run a program with output, only in the background.  So there is 
no output when the systems hangs.


Example to Duplicate Problem
----------------------------
Just running several dd commands at the same times.  I just put it in a 
loop and ran the same command but change the output file name.  

dd if=/dev/zero of=/buffer1/tmp.file$i bs=1k count=600000 &

thats basically it, except forthe loop that i executed 4 times.


Environment
-----------
I saved a script file to showsome of the setting on the environmen.  It is 
saved as an attachment.


The SCSI hard disk that we are using is: IBM-DDRS-34560-S97B cyl 8186 alt 
2 hd 5 sec 218) and approx 4GB.


Please let me know if this is a bug or not....
