I will try nohdparm, but can you explain to me what is for?

hdparm is tool to setup some properties of ATA/SATA harddrives

during boot, when devices are being discovered, there is rule for /dev/sd* devices to be passed to hdparm tool. with default settings in /etc/hdparm.conf, hdparm tries to set spindown for it. but I had some experiences with this not working under some conditions (probably types of drives) causing wrong instructions sent to /dev/sd* causing lags, timeouts, corruption at the end.

and your dmesg reminded me to this. Beta2 with nohdparm means hdparm is not called and spin down is set by usbmount (service to provide usb hotplug mounting) with additional checks whether drive could be set to spindown (checks like drive being rotational, supporting APM, aupporting other power management commands).
