Tails is affected by that bug (https://labs.riseup.net/code/issues/8778); in case it may help asserting the severity, comment #16 there (and some further ones, particularly #19 and #22) have additional data about what exact vcpu model and features are affected. I've rebuilt the mesa package with the patch from https://freedesktop.org/patch/34445/, and it fixes things for me, at least with `-cpu qemu32'. I've asked the other Tails developer (Cc'd), who is also experiencing this bug, to try and reproduce my results. => I believe at least one of these bugs should be reassigned to the mesa package. I'll let the maintainers decide about that and about the potential RC-ness. If it helps, I can also do a more complete series of comparative tests with various vcpus. > Would use of llvm-3.4 for jessie be acceptable to the Mesa maintainers? > According to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=775235#15 > that fixes at least one of these merged bugs, perhaps all three. I suspect that the release team will find that rebuilding mesa with a different compiler is more invasive and risky, at this stage of the release cycle, than applying a relatively simple patch. (The good news is that we might get a release team member's opinion for free while asking to the mesa maintainers :) > Alternatively, would it be useful information for the Mesa maintainers > if people tried Mesa 10.4.2 on affected systems? I can do that if it helps, although I suspect it's too way late to let that one migrate to testing.
