I will try it later, I could not rebuild the system now.
Are there anyway to turn it off on the command line?

I mean it fails(hang) most of time when I try to mount the reiserfs with
120G size after "mkreiserfs".
As you notice in the system status below, the CPU is occupied by the system
by 99.6(8) %.
I do not know why?

Sorry! What is "sysrq"?

Sorry I misled you!
This problem happens most of time at "mount", but it happens sometimes at
"mkreiserfs".

One more strange thing is "failed to generate UUID" as follow;

-------------
root@praetorian:/# mkreiserfs  /dev/hdg1

<-------------mkreiserfs, 2002------------->
reiserfsprogs 3.x.1b

mkreiserfs: Guessing about desired format..
mkreiserfs: Kernel 2.4.5-rmk4 is running.
failed to genetate UUID
<----------------------Why????
Format 3.6 with standard journal
Count of blocks on the device: 30015208
Number of blocks consumed by mkreiserfs formatting process: 9127
Blocksize: 4096
Hash function used to sort names: "r5"
Journal Size 8193 blocks (first block 18)
Journal Max transaction length 1024
inode generation number: 0
UUID: 00000000-0000-0000-0000-000000000000
------------------------

Do you have any clue from it?

Thanks,
