OK, that in itself looks related to having a bad block group error:

ide1(22,66)): load_block_bitmap: block_group >= groups_count - block_group =
131071, groups_count = 94

but the real question is, where did this happen:

transaction.c:227: "handle->h_transaction->t_journal == journal"

Please use "ksymoops" to decode the call trace, and I'll take a
closer
look.
