VFS problem
Sorry if this problem has already been disscussed.
I run an linux box with a HD 30Go/reiserfs .
I tried several 2.4 kernel ( 2.4.2 , 2.4.3 , 2.4.4-pre3 , 2.4.3-ac7) After a random time I've got a fs problem which lead to :
-first a segfault of a process which reads/writes on the partition ex:
[jal@skippy prog]$ ./configure
....
ln -s dialects/linux/machine.h machine.h
Erreur de segmentation ( SEGFAULT )
-and then the partition freeze .Any attempt to read/write on it leads to
put the process in a D state and makes it unkillable. [/var/log/kernel]

I will try with ac9 but I'm not really sure of the result..

Rectification : the VFS disk change is a normal event , and has no interaction with the kernel NULL pointer.
So , does someone has a clue ?

Hmmm, are you sure there aren't any reiserfs messages on screen or in the log?

there's nothing on the screen neither ine the logs about reiserfs .. the onlys thing is that pointer NULL reference ..
