Bug Description
Booting the Alpha 1 image, I get stuck at a point where I'm seeing console messages on the screen
...
* Starting init crypto disks...
Alignment trap: not handling instruction ed9f9b93 at [<000626f2>]
Unhandled fault: alignment exception (0x011) at 0x00062942
(The previous two messages repeat 13 more times with the same addresses)
I can alt-f2 and switch to another console, dmesg also shows another message at the end of that:
Recursive core dump detected, aborting
I was able to manually bring up the network, but trying to scp anything such as dmesg info across to another machine resulted in a few more Alignment trap/Unhandled fault errors, and ssh failed.
Trying to run some commands, such as apport-cli, fail immediately with these errors.
I straced apport-cli as an example, and at the end, I had:
close(3)
munmap(0x40020000, 4096)
Alignment trap: not handling instruction eddf7a13 at [<0002b8d2>]
Unhandled fault: alignment exception (0x011) at 0x0002b922
--- SIGILL (Illegal instruction) @ 0 (0) ---
Alignment trap: not handling instruction eddf7a13 at [<0002b8d2>]
Unhandled fault: alignment exception (0x011) at 0x0002b922
Does this appear more likely to be kernel, or toolchain? I did not have this same problem on a different SoC with alpha1

does a lucid chroot in karmic work?
