Initramfs does not find the root device when an usb external drive is plugged-in

[Jean Dumont]

Since the installation of linux-image-2.6.31.16-generic, I have a problem with intramfs not finding my root device

How to reproduce:

I plug an external usb drive and wait for it to be mounted, then I shutdown my machine, I turn the power off on the external drive and cold boot.

After a few seconds I got a message from intramfs stating that it can not find my root device and it drops me into a shell

Then I do a warm reboot (ctrl-alt-del) and everything is back to normal

If I umount my external drive before shutting down, everything works as expected.

I don't know if this has anything to do with the new kernel, but I did not experience this behaviour before installing 2.6.31.16

If you need any extra informations, please contact me

greetings

Jean

[Jean Dumont (jean-dumont)]

Well, the kernel update of today seems to have cure the problem

Sorry for the useless noise

Thanks for the update, I'll go ahead and close this out.
