Title:
3.4.0-4-goldfish in i386 emulator: kernel NULL pointer dereference at
000000bc
Status in “goget-ubuntu-touch” package in Ubuntu:
New
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Current Ubuntu Touch images cause a kernel panic at boot:
$ sudo ubuntu-emulator create --channel=ubuntu-touch/devel-proposed
--arch=i386 devel-proposed
The current revision as of the time of reporting is 160. This did not
yet happen with earlier revisions. I re-tested with --revision=157 and
that does not crash (it also doesn't show unity due to bug 1349444,
but that's a different story :) ).
$ ubuntu-emulator run devel-proposed
You'll see the first-time wizard. Click through, then unity8 is
supposed to restart. Instead, the kernel oopses:
* Setting up X socket directories... [ OK ]
* Starting automatic crash report generation: apport [ OK ]
