I dunno what you wanted to do by:
> dd if=/dev/hda4 of=/tmp/testing.img bs=1024M count=2k
Becuase it won't read 1024M into memory at once, says memory exhausted..
So I did..
bash-2.04# cd /storage
bash-2.04# dd if=/dev/hda2 of=testing.img bs=1024k count=2000
2000+0 records in
2000+0 records out
bash-2.04# ls -sh testing.img
2.0G testing.img
bash-2.04#
No problems here (nothing in dmesg, no crashing..) Course interactivity in X was total
shit while dd was
running =\.
