1. I have updated bootcode just in month or so before the failure.

dd if=/boot/zfsboot of=/dev/slice count=1 bs=512
dd if=/boot/zfsboot of=/dev/slice skip=1 seek=1024 bs=512

Yes, this means revision 206815 was not there.

2. After the computer fails this time I haven't touched bootcode.

I see your point and I'll try to retest on recent STABLE. This changes
nothing though.
http://svn.freebsd.org/viewvc/base/stable/8/sys/boot/zfs/zfs.c?r1=199634&r2=206815&pathrev=206815

I'll try to retest writing on recent STABLE on i386. Maybe not the
bootcode is culprit here.
