Sorry to change the status. I'm not that familiar with Launchpad and
was looking for a commit that fixes this bug.

@Ricardo I did not have such a problem and it ran all simple programs just fine
(top, ls, cd, cp and so on) on my armv5t. Though I did not cross-compile, but
natively compiled qemu on the box itself.
It would be cool to have it working, but I don't think it will happen any time
soon. I just bou
I had exactly the same behavior with a patched 0.14.1. Wine doesn't work
and that was the reason I was so eager to run qemu.

YES! That did the trick!
Though, with this patch I was unable to compile qemu 0.15rc1. I suppose
the patch wasn't meant for it, but with 0.14.1 it works flawlessly.
Also, I had to do echo 2 >/proc/cpu/alignment as was mentioned by Peter.
I hope the patch gets applied to the main tree.

Awesome Artyom! I'm compiling now. I will report back if this patch
works for arm as well.

Ok, it seemed as though "ls" worked from "strace -ff -o ls-strace-
alignment-2.log chroot /i386 /usr/bin/qemu-i386 /bin/ls"
so I tried to execute the package manager:
[root@Plugbox ~]# chroot /i386 /usr/bin/qemu-i386 /usr/bin/pacman -Suy

Garbled text might have been fixed in the recent versions as it seems.
Even with User faults == 0 the text is not garbled.

Did you modify some code to get it working on your armv5 ?

You are correct in saying that only user mode does not work. I did
install windows 98 in qemu VM and it worked fine (aside from the fact
that it was slow :))

Do you think it will ever get fixed in a reasonable amount of time(or
ever) or am I better off just getting an x86 low power board to run x86
binary-only code?

The hardware I use is pogoplug with plugapps linux. I think any plug computer
