panic configuring raid 1

[horio_(_at_)_acm_(_dot_)_org]

Hello,

I am trying to configure mirroring disk with my slimed down kernel but
am getting panic at the very early stage of initial configuration.
I have not succeeded in "raidctl -i" with the kernel as yet.

On the other hand, with the kernel generated from GENERIC with options
raid uncommented works fine. I may have stripped off necessary code for
raidframe or added code incompatible with it at runtime. But I cannot
find the real cause of panics so far.

Since the latter is more than 3.2mb but the former is less than
1.6mb (although unworkable now), I want to know my real error. Will
you help me ?

I attached raid.2 file I use to configure raid2d (this is likely to be
raid2c, as opposed to man page), the log of panic-reboot-panic
sequence. Sorry for this long message. As attaching kernel config file
makes this too long, I did not attached it.

One more question. Is FFS_SOFTUPDATES compatible with raidframe, and makes
sense on my mirroring configuration ?
