Hi All,
I am using Linux kernel 2.6.23.
The kernel command line is:
console=ttyS0,115200 root=/dev/nfs
nfsroot=172.20.69.140:/home/fsroot,nolock rw ip=dhcp mem=exactmap
memmap=6...@0 memmap=2...@1m
So when kernel boots it mounts the root file system over the network.
I then configured and compil

Back to my problem. I am not very clear what is still reason for the delay.
Here is the part of the boot log:

1 usecs
[5.582773] calling memmap_init+0x0/0xaa @ 1

1) dd program issues number-of-writes="count" of size="bs". So in your
case, there will be 10 read sycalls of size 4096 bytes from /dev/zero
and 10 write syscalls of size 4096 on "nnn". You can verify this using
strace utility.
2) block size given at a time of filesystem creation affects the

Hi nidhi mittal hada,
a) 'dd if=/dev/zero of=nnn bs=4096 count=10'
b) 'dd if=/dev/zero of=nnn bs=4096 *10'
in a) bs=4096 force ibs=4096 and obs=4096
in b) bs=4096*10 force ibs=4096*10 and obs=4096*10
ibs means read bs bytes at a time
obs means write bs bytes at a time
that means the two ways rea
