Hi Yuri, I'm running the acceptance tests to reproduce this issue, but has not reproduced it now, since it's not 100%, do you have any other advise for reproduce/verify it more easier? Thanks~ Peixiu And I also want to know which job hit BSOD during acceptance testing on Win8.1? I tried to run the whole acceptance loop some times, but not hit BSOD occur. Thanks～ Peixiu As I remember after discussion with Yuri, it was caused by running fwcfg64 driver on 32-bit Windows, but at that date the driver did not yet have a 32-bit version. So, to reproduce it fwcfg64 must be run on 32-bit Windows. The 32-bit version were introduced in upstream commit https://github.com/virtio-win/kvm-guest-drivers-windows/commit/f1ba15c6cc09a191807342e250a00fb0f3f40564 .

Hi Viktor, If possible, Could you help to create a downgrade test build with 32-bit support? And BTW, Bug 1983947 - [RFE] Add support for fwcfg64 driver - 32 bits used to track fwcfg 32 bits support, it has been remove to RHL9.1, but as I known, this fix has been included in build 216, will released with RHEL9.0, so If this fix is related to 32 bits system, Is it better merge both on the same target release? Thanks a lot~ Peixiu Not reproducible for now, moving this to VERIFIED since regression test passed on 64 bit Windows OSes. We will open new bz if detect issue on 32 bit fwcfg when it is released in future~ Thanks~ Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
