Description of problem: Booting failed to find root device because disks have not yet spun up. Version-Release number of selected component (if applicable): mkinitrd-6.0.71-2.fc10.i386 How reproducible: Every time. Steps to Reproduce: 1. Install 2. Boot Actual results: Boot fails Expected results: System boots Additional info: The root file system is RAID 1 across two USB disks. The boot file system is RAID 1 across two USB disks and 1 CF card. The init script in the generated initrd contained this line: stabilized /proc/bus/usb/devices That line waited for both the USB disks to be found. However it did not wait for the disks to spin up and the partition tables to be loaded. So when the script continued, it complained that it could not find the root file system. Inserting sleep 20 around that place worked around the problem. Contents of mdstat after booting: [root@alix1 ~]# cat /proc/mdstat Personalities : [raid1] [raid6] [raid5] [raid4] md6 : active raid1 sda6[0] sdb6[1] 2096384 blocks [2/2] [UU] md1 : active raid1 sdb1[0] sdc1[2] sda1[1] 3879552 blocks [3/3] [UUU] md7 : active raid1 sda7[0] sdb7[1] 970542720 blocks [2/2] [UU] unused devices: <none> [root@alix1 ~]#

The fix is described in bug #466607 comment #57. Can you test that and post results there? If that works, you can close this as a duplicate of bug #466607. I see you have already modified your init to get a bootable system, but you can also work around this by add the option "scsi_mod.scan=sync" to the kernel command line.
I tried adding "scsi_mod.scan=sync" to the kernel command line. With that it waited for one of the two USB disks to spin up and load the partition table. That's enough to get the system to boot, but would break the raid, so I would have to add the other partition back into the raid on each boot (followed by 14 hours of resync).

Try regenerating your initrd with the fixed mkinitrd that fixes this. *** This bug has been marked as a duplicate of bug 466607 ***
