Bad news. v3.18-rc2-utopic screws things up completely and the system doesn't boot.
The symptoms are as follows: - the initramdisk doesn't show the password prompt to unlock the full disk encryption. - the external usb keyboard doesn't work (i.e. I can't use ESC to hide the splash screen on the external keyboard but I can use ESC on the internal keyboard. However it is not a complete USB outage since both, the keyboard and mouse are showing lights. The external keyboard does work during grub though) - after hiding the splash screen it tells me something about not finding any volume groups (not really surprising if it skips the disc encryption...) I tried to run dpkg -i on the three kernel packages again to re-generate the initramdisk and look for errors. I didn't see any relevant messages and it still failed to boot. The kernel packages I used were linux-headers-3.18.0-031800rc2_3.18.0-031800rc2.201410262035_all.deb linux-headers-3.18.0-031800rc2-generic_3.18.0-031800rc2.201410262035_amd64.deb linux-image-3.18.0-031800rc2-generic_3.18.0-031800rc2.201410262035_amd64.deb I dare say, there is another issue at work here than the one we were dealing with so far. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1384041 Title: [Dell Precision M3800] USB is dead after resume from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1384041/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
