I get the impression "raw" is ignoring your input parameter
to use /dev/raw/rawsdb and is using /dev/raw/raw<N> instead.
So it looks like you are comparing the wrong data...
root@debian:/dev# raw --help
raw: invalid option -- -
Usage:
raw /dev/raw/rawN <major> <minor>
raw /dev/raw/rawN /dev/<blockdev>
raw -q /dev/raw/rawN
raw -qa
What does "dd if=/dev/raw/raw2 of=/tmp/o_raw2 bs=512 count=8" result in?
Anyway, it looks broken for me too.
I tried using raw on 32-bit 2.4.20-pa28:
raw /dev/raw/raw1 /dev/sda
raw -qa
/dev/raw/raw1: bound to major 8, minor 0
dd if=/dev/raw/raw1 of=/tmp/raw1.o count=8
/usr/bin/od -Ax -t x /tmp/raw1.o

/dev/sda is the boot disk for this machine.
root@debian:/dev# /usr/bin/od -Ax -t x /dev/sda | less
