I am using Mandriva which has mkinitrd based on RedHat (current version in 6.0.63). With 2.6.28 it sporadically fails (or I should rather say, it sporadically manages) to created block devices in initrd which of course prevents kernel from finding root later.
The control flow is
1. mkblkdevs (I assume, it is for any built-in driver) 2. load modules, needed for disk access/file system 3. mkblkdevs again 4. mount real root etc etc etc
First mkblkdevs will initially traverse /sys/block and create all it finds there. It is empty in my case (no built-in driver).
Second mkblkdev will notice that device tree was already initialized and will not descend into /sys/block but rather listen and process to hotplug events generated in step 2. At least that is how I interpret nash code.
So it looks like something has changed between 2.6.27 and 2.6.28 regarding event delivery. It looks like race condition. I do not see any pattern except after several attempts it would suddenly boot.
I tried both IDE and PATA, both show the same problem.
Any idea?
