The double fault is particularly worrying as it suggests the problem is kernel or qemu. I've put a script which tends to reproduce the issue into the bugzilla. When you say you've seen ld.so faults on real hardware, have you any more details? Are they happening often? Just ld.so? I need to know if this is a qemu issue or on real hardware too since the latter is a release blocker and extremely serious. Cheers, Richard
