Description Tadej Janež 2011-07-02 13:52:08 UTC 
Description of problem:
I've been bitten by a subtle problem. Recently I've bought an HP EliteBook 8560p with 2 USB 3.0 ports. Not caring much, I connected the Live USB stick to one of the USB 3.0 ports and the boot process failed with the following cryptic message:
[   27.750031] dracut Warning: No root device "live:/dev/disk/by-uuid/97BF-159F" found.

The same Live USB worked fine on other systems, so I was puzzled.

Then I tried putting the USB stick on another non USB 3.0 port and it worked like a charm!


Version-Release number of selected component (if applicable):
Fedora 15 x86_64 Live Desktop

How reproducible:
Always.
Comment 1 Josh Boyer 2011-09-26 19:14:44 UTC 
The USB 3.0 driver (xhci) was built as a module and likely not included in the default initramfs, which means booting from a live USB key in an 3.0 port would not work.  This has been fixed in F16 and should work with the Beta release coming up.  We can't really fix released media for F15.
