Hope i didn't miss to much followups ;-)

Seems to me as a well known scenario i've had testing my logical
volume manager (hopefully the LVM will make it's way
into 2.2).

All the time i tried to make large filesystems greater some GB,
my machine locked up. Buffer management trouble ahead...

So...
Added a check to fs/buffer.c ( at the beginning of grow_buffers ()) to keep
cache buffers in limit (10MB in case of my 64MB box). This doesn't
stress the buffer management too much until it's REALLY fixed.

This workaround let the problem disapear for me working
with filesystems up to 25GB in size.

Please tell me, what it does for you.

Peace hacker,
Heinz
