But I think we still have a problem.
I'm using 3.4.0-rc7, have pulled all fixes from James "fixes" branch,
and Dave's "vmlinux.lds" patch.
The 32bit machines (715/64 and B160L) boot nicely into userspace.
The 64bit machine (C3000) crashes directly when switching to userspace.
Do we still have another problem somewhere?
Or is it introduced because of the vmlinux.lds patch?
(Reminder: without the vmlinux.lds patch the C3000 hangs directly at
bootup after printing memory information...)
I'm not seeing it on my rp3410 ... I'm going to have to find the J box
(which I think is closest to your C3000 ... that's an astro system) and
boot it.
[crash log removed - new one see below]
What this says is something went wrong in the tmpalias space because
it fell through to the fault path. How much memory does this system
have (and what's the layout map)? It's 64 bit but you're booting it
with a 32 bit kernel ... I'm wondering if there's no space for
tmpalias. James
James, here is the full kernel log. Does this help?
