[lubuntu] Can't install Lubuntu 16.04 (USB key): "usb usb1-port7: over-current condition"

Hi everyone,

I'm trying to install Lubuntu 16.04 i386 from an USB key (that proved to be working normally with Kubuntu & Xubuntu 16.04 installers) on an old Pentium 4 / 2 GB RAM PC.

At boot, I can select my language and get to the options menu, but as soon as I select any of the options (like "Try Lubuntu ..."), it looks like the installer freezes for ~ 1 min (still displaying the options menu), then displays a black screen, followed by a short message - too fast for me to read, then displays a blinking cursor at the top left.

When I switch to display tty1, I can see several errors (read below) for a short time, followed by the login prompt, but everything soon disappears, until I press Ctrl+Alt+F1 again, same messages appearing and disappearing, etc. etc. Consequence: I'm unable to login to gather more information from logs.

usb usb1-port7: over-current condition
[drm:intel_parse_bios [i915]] *ERROR* Child device config size 27 is too small.
[drm:i915_gem_init_stolen [i915]] *ERROR* conflict detected with stolen region: [0x7f800000 - 0x7ffe0000]

Ubuntu 16.04 LTS lubuntu tty1

lubuntu login: _

The sole similar error I could find is in this thread ("[drm:intel_parse_bios [i915]] *ERROR* Child device config size 27 is too small.") but I'm not facing anything relating to 'fsck'.

Note: I checked the MD5 sum of my downloaded ISO and it looks OK: 1b5dc31e038499b8409f7d4d720e3eba lubuntu-16.04-desktop-i386.iso

Thanks in advance for your opinions.

In the meantime I'll dig the 2nd part of the errors ("[drm:i915_gem_init_stolen [i915]] *ERROR* conflict detected with stolen region").
