Comment 13 for bug 921208

Hi Rolando,

thanks for this detailed report. Since you mention that Windows7 runs
fine for you, you gotten me really curious. Could you please post
the exact command line you are using (e.g., what additional hardware you
are emulating, etc.), the build version, the host system, etc.

I'm pretty sure that the BSOD occurs in some specific (but default)
Windows driver, because I can boot and run Win7 without problems in
safe-mode (where this specific module/driver might not be loaded or
executed). BTW, I'm emulating a 64bit Windows, same for you?

Further, I have actually traced the execution of Win7 to a point where
I even see WHY a BSOD occurs. The code executes a BOUND instruction that is
i386-only, so not available in 64bit mode. A wild guess would be that this happens
because some CPU-ID instruction returned an invalid bit at some point
causing windows to install an invalid driver or go down a wrong path.

A last question: I assume you installed Windows with KVM, right?
Because 1) without it it's just too painfully slow :) and 2) the
installer crashes for me without KVM.

Thanks!
