Title:
Unable to boot without 'noapic' boot flag
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
When I try and boot 12.10 from a live CD without any tweaks, it
crashes on a black screen and requires a hard-reset. The only way to
get around it is to enable the 'noapic' boot flag.
This problem has been present for the past couple of releases, and it'd be
great if it actually got fixed. I've reported it before, but I've made a new
bug report now to provide updated dumps etc.
It's worth noting that at one point it was actually fixed in the mainline
kernels, see comment #7 on Bug #903558.
I also had some success with a custom kernel config file someone provided me,
but I lack the skills to identify the solution from that.
I'd love to get some help with this bug. Please.
