[Bug 1384041] Re: [Dell Precision M3800] USB is dead after resume from sleep

 

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.

Title:
  [Dell Precision M3800] USB is dead after resume from sleep

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After resuming from sleep (suspend to ram), all external usb ports are
  dead.

  The laptop's built in keyboard and synaptic touch pad (I think it is
  vonnected via internal usb, but not 100% sure) still work.

  Only a complete power down and reboot seem to bring back the devices.

  The problem does not happen with the previous kernel 3.13.0-36.
