I found the string 'Partition Check:' in check.c 
at /usr/src/linux/fs/partitions.
I think init is invoked after that
and check.c seem to be checking partition table,
so I think bad hdparm.conf can't become the reason.
(in fact, I turned it on just a few days ago.)

below is my hdparm.conf.
very simple.

# grep '^[^#]' /etc/hdparm.conf
quiet 
/dev/hda {
        io32_support = 3
        dma = on
}
/dev/hdb {
        io32_support = 3
        dma = off
}


any suggestions will be greatly appriciated.
