Hi John, Nitin,<br><br>I think i have not explained well about the method for the hang.<br><br>1) insmod xvmalloc.ko; # I use 0.5.3 version<br>2) insmod lzo-faster.ko; # I use a modified form of compressor, this helps me to boot my application faster.<br>
We can try this same by inserting compressor and decompressor modules which is given in the compcache release. <br>3) insmod compcache.ko;<br><ul><li> State 1</li></ul><div style="margin-left: 40px;">mkfs.ext3 /dev/ramzswap0<br>

My main motive is not to run the compcache block node as a swap partition. I would like to use this partition for shared memory. My application has to do lot of IPC's but i do not have much memory on board so i have decided to use compcache block device node as a generalized block device.<br>

How about this:<br>
- Create a small tmpfs partition, say 64MB and create filesystem over this.<br>
- Create ramzswap device (probably with a backing_swap) with memlimit of say, 1GB.<br>
<br>
This extra level of indirection using tmpfs effectively gives the same effect as a 'generic ramzswap device'.<br>
I think this is what John suggested.<div class="im"><br>

Also I have checked formatting this node with some block as ext3, this works perfectly well.<br>
With ext2 it is having some issue i will look in to it, But with fat 16, 32 I see a hang in the system which is a result of the analysis i have done. I will let you know f i find some thing.<br>
<br>
1) swapon /dev/ramzswap<br>
2) mount -t tmpfs -o size=1G,nr_inodes=10k,mode=0700 tmpfs /space<br>
<br>
<br>
I do not want it as swap partition<br>

I cannot think of any other method than tmpfs+ramzswap for your case.<br><font color="#888888">
