Don't worry about those if you have memory-backed RAID card. BIO_FLUSH
is there to tell the disk to flush its write caches, but if it is
memory-backed, there is low risk on losing unwritted data.

This is not the cause of your problem.

BTW. "journal ... clean" means that there was clean shutdown and there
was no need to replay journal, while "journal ... consistent" means that
there was unclean shutdown and journal replay was successful.
