The error: sh-2006: read_super_block: bread failed (dev md0, block2,
size 4096)
My config works fine with kernel 2.6.12. 2.6.13 (I've tried everything
from make oldconfig to a complete
make xconfig walk-through) panics with error above no matter how I
compile it.
Could I really have a bad superblock? Why would my 2.6.12 work if that
were the case? Also, I tried replacing mdadm.conf with output of mdadm
--detail -s Doing so caused 2.6.12 to fail, too (though on md5 not md0,
so I could boot single user)
My distro is Gentoo. Any help appreciated! (I want to follow ~stable)
