Barak, you mentioned on Sat, 03 Mar 2007 02:22:18 +0000 that you were
seeing success with a stock Debian kernel.
I can report that it fails under at least some conditions, on my
freshly-installed system of etch (netinst 40r1) using a stock Debian
kernel, though nearly a year later. Mirroring your post:

But:

Now, I installed this system from scratch the other day, from the stock
netinst CD, and raidutil worked for me the first time. I since
re-installed it, after modifying /boot/initrd.img-2.6.18-5-686 to
blacklist i2o_block and i2o_core because d-i was using /dev/sd* instead
of /dev/i2o/hd*. (Google turned up this workaround.) Since then, based
on things I read in this bug, I put things back: modified
/etc/modprobe.d/blacklist to remove i2o_block and i2o_core, and to now
blacklist dpt_i2o instead; added i2o_config to /etc/modules, re-ran
"update-initramfs -u" and fixed /boot/grub/menu.lst and /etc/fstab to
refer to the /dev/i2o/hd* devices. The system boots and runs fine with
i2o_block et al, but raidutil is still unhappy. In fact:

That's about as far as I can take it in that direction. It's something
fairly subtle, and just switching to i2o_config and friends isn't
_quite_ enough. (That's a bug, IMO. If it threw a meaningful error
instead, pointing at the thing that needed fixing, that would be swell.)
On yet another machine (this time at my colo), I had a failure
yesterday, and success today! It looked like this a minute ago:
[EMAIL PROTECTED]:~$ sudo raidutil -L controller

[EMAIL PROTECTED]:~$ sudo raideng /VERBOSE /NOKILL

That didn't do it. Had to "kill -9". But then!

It works! And this on a system that's using sd* and dpt_i2o, with
i2o_{block,core} still blacklisted in initrd:
[EMAIL PROTECTED]:~$ lsmod | egrep i2o
dpt_i2o 27900 6

crw-r--r-- 1 root root 151, 6 2007-12-16 02:22 /dev/dpti7
(I had made those manually.)
[EMAIL PROTECTED]:~$ mount | egrep i2o
[EMAIL PROTECTED]:~$ mount | egrep sd

/dev/sda6 on /var type ext3 (rw)
[EMAIL PROTECTED]:~$
So that's something. If you're running dpt_i2o and you have to mknod
/dev/dpti17 et al, be sure to clobber and restart the raideng, but good.
On a system using i2o_block+i2o_core, I dunno. YMMV/HTH.
