Re: Partition table not loaded; Boot failes for Debian testing

[Raphael Bossek <raphael.bossek@googlemail.com>]

Hi Andrei,

I've checked the /dev/disk/by-uuid directory after initrd console appears. There are no entries until hdparm -z /dev/sda is called. hdparm -z /dev/sda force the kernel to reload the partition table. I'm sure that the driver is up and runing because dmesg|grep sda show that the partition table was recognised!

Who is responsible for /proc/partitions ? Is there a way to prevent udev to be started by kernel option ? The problem I see is that mounting /dev/sda2 (which is the ext3 root partition) failes with "Device or resource busy" after hdparm -z /dev/sda is called. There is something going on which is not right.

Regards,
Raphael

Ok, scrap that idea.

Could you check if your initrd contains the correct module for your SATA
chipset? If not adding it might solve your issue.
