Hi,

Yesterday I tried to increase the value of strip_cache_size to see if I can 
get better performance or not. I increase the value from 2048 to something 
like 16384. After I did that, the raid5 freeze. Any proccess read / write to 
it stucked at D state. I tried to change it back to 2048, read 
strip_cache_active, cat /proc/mdstat, mdadm stop, etc. All didn't return 
back. I even cannot shutdown the machine. Finally I need to press the reset 
button in order to get back my control.

Kernel is 2.6.17.8 x86-64, running at AMD Athlon3000+, 2GB Ram, 8 x Seagate 
8200.10 250GB HDD, nvidia chipset.

cat /proc/mdstat (after reboot):
Personalities : [raid1] [raid5] [raid4]
md1 : active raid1 hdc2[1] hda2[0]
      6144768 blocks [2/2] [UU]

md2 : active raid5 sdf1[7] sde1[6] sdd1[5] sdc1[4] sdb1[3] sda1[2] hdc4[1]
