I found a solution to this problem, recreating file "casper/initrd.gz" after updating script "/init". This update consists to insert the following lines before line containing "maybe_break mount" : modprobe -r libusual sleep 3 modprobe usb-storage sleep 5
The second line is mandatory to let "libusual' remove smoothly before loading "usb-storage". Moreover, I successfully performed a non-regression test with a "slow" machine which was not concerned by this problem. -- Failure to boot from USB - Dell Latitude XT https://bugs.launchpad.net/bugs/364538 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
