lkml thread "current linus bk, error mounting root"

[Jon Smirl]

I just sent this to AndrewM in reference to the lkml thread "current
linus bk, error mounting root".

The problem is that something in the bk tree after 2.6.11 caused the
mount of my root SATA device to fail.
--------------------------------------------------------------------

No, I think Jens wants all of the distributions to fix it. I have
filed a bug with Fedora on it.

Something changed in the timing for loading drivers during boot. You
used to be able to do:
modprobe ata_piix
mount /dev/sda1

Now you have to do this:
modprobe ata_piix
sleep 1
mount /dev/sda1

I suspect the problem is that udev doesn't get a chance to run anymore. 
The sleep 1 allows it to run and it creates /dev/sda1.
Build ata_piix in and the problem goes away too.

Jens is right that this is a user space issue, but how many people are
going to find this out the hard way when their root drives stop
mounting. Since no one is complaining I have to assume that most
kernel developers have their root device drivers built into the
kernel. I was loading mine as a module since for a long time Redhat
was not shipping kernels with SATA built in.
