I made another experiment and upgraded the host to 5.15-rc7 which contains your fixes and made the guests build gcc-10. Interestingly, this time, the gcc-10 build crashed the guest but didn't manage to crash the host. I will update the guest to 5.15-rc7 now as well and see how that goes. > Can you try running your guests with no SMT threads? > > I think one of your guests was using: > > -smp 32,sockets=1,dies=1,cores=8,threads=4 > > Can you change that to: > > -smp 8,sockets=1,dies=1,cores=8,threads=1 > > > And something similar for the other guest(s). Sure. I will try that later. But first I want to switch the guests to 5.15-rc7 as well. > If the system is stable with those settings that would be useful > information, and would also mean you could use the system without it > crashing semi regularly.
