Public bug reported:
I've installed 15.10 Wily Werewolf to my USB stick via usb-creator and restart
the laptop
on boot, I'm asked for the language and if I want to install or try a live
session
I select try life session, the dialog disappears and the machine is frozen
Next try:
boot to selection dialog
switch to console crtl+alt+F1 (takes a moment)
issue alt+syreq+1 and alt+sysreq+t ... both answer "operation is disabled"
switch back to X ctrl+alt+F7 & click try live session
immediately switch back to console ctrl+alt+F1
watchdog detects hard lockup a few seconds later
see attached screenshot
reproduced also in beta1 of wily werewolf ... a month ago I imagine the
beta was still starting, as for bug #1492840. But I've reformated the
stick meanwhile and cannot really guarantee, that I didn't confuse the
multiple ISO's I tried in short time.
version information:
kernel 4.2.0-16-generic #19-Ubuntu (4.1.0-3-generic #3-Ubuntu)
libqt5sql.so 5.4.2 (both)
currently running Kubuntu 15.04 on the same hardware
