Get system rescue CD version 2.8.0 here:
http://www.sysresccd.org/Sysresccd-versions
Verify md5 checksum: 450305b2c3ac12d5c97ff849ca178586
Try to boot:
./x86_64-softmmu/qemu-system-x86_64 -net user -net nic -snapshot -cdrom \
~/images/systemrescuecd-x86-2.8.0.iso
Select option: all files cached to memory.
Error: XZ compressed data is corrupt.
Try version 1.2.2 (in F18)
qemu-system-x86_64 -net user -net nic -snapshot -cdrom \
~/images/systemrescuecd-x86-2.8.0.iso
Boots fine, gets to keyboard prompt.
Try with kvm:
./x86_64-softmmu/qemu-system-x86_64 -enable-kvm -net user -net nic -snapshot -cdrom \
~/images/systemrescuecd-x86-2.8.0.iso
Boots fine, gets to keyboard prompt.
Didn't try bisecting yet.

Note: tried version 2.1.0, that boots fine.
Tried version 3.5.0, that hangs on boot
(or maybe it's just too slow? gave up after 15 min).
In all cases -enable-kvm makes it work fine.

Reproduced it too (by chance :)) with Fedora 16. Trying to bisect now.

Hmm, no, must be a different thing. It was in a "seemingly innocuous"
patch at the top of my tree, and system rescue CD works for me. No XZ
error and it boots fine in 3-4 minutes.
BTW, the cache option fails to cache things for me due to lack of memory
(requires 512M). I also tried with "-m 1024", but it still succeeds.

I am also not able to reproduce the problem, neither with 1.4.0 nor with
current master.

2.0.8?
Hmm maybe the issue is I'm on a 32 bit host ...

It's an important information. With it I am able to reproduce the issue.

Ah. I'll see what I can do. Downloading 350M might not be possible while I'm
traveling though, so any help producing a reduced test case would be appreciated.

I'll try to work on that. For now I have determined the problem is on
the gen_shiftd_rm_T1 side, the gen_shift_rm_T1 part is fine (at least
it's not the one triggering the issue).
