Hi,
In our labs, we encountered a kernel crash, while stressing scsi
device add/remove code path of 2.6.28 kernel. lsscsi output on my
machine looks like this:
*******Start******
[root@IMIT2S005 ~]# lsscsi
[0:0:0:0] disk ATA ST3250620NS 3BKS -
[0:0:1:0] disk ATA ST3250620NS 3BKS -

[5:0:0:0] disk Linux scsi_debug 0004 /dev/sdb
*******End*********
I have written script which would recursively add/remove the lone lun
of scsi_debug device. My script looks like this:
********Start******
[root@IMIT2S005 temp]# cat s.sh
while [ true ]
do
echo "scsi remove-single-device 5 0 0 0" > /proc/scsi/scsi
echo "scsi add-single-device 5 0 0 0" > /proc/scsi/scsi
done
[root@IMIT2S005 temp]#
********End********
When the above script is run for approximately 10 seconds, we started
to see the following messages and finally NULL pointer dereference.
********Start*******
