Hello, Maat struggles for days to find why his windows10 crashes randomly on a virtualmachine (probably also kvm, and other). References: https://forums.virtualbox.org/viewtopic.php?f=7&t=101667&start=75 https://lwn.net/Articles/786239/ Best comment : https://www.virtualbox.org/ticket/20180#comment:8 For short: Intel 10th gen proc has the new feature "Split Lock Detection" added in from the kernel of Linux. And it seems that windows10 do that. On our side, we can't detect if a windows10 guest installed, but we can add a checkbox in our drakboot when the CPU has this feature with such comment: > ☐/☑ Avoiding windows10+ crashes by disabling "Split Lock Detection"
Thank you for this report. From the 'best comment' above: "The Linux kernel added Split Lock Detection between kernels 5.4 and 5.8, enabled by default. On the Linux host, it can be disabled with the kernel parameter split_lock_detect=off. This can serve as a workaround for the time being." It is a problem for running Windows in a virtual machine; 'kernel parameter split_lock_detect=off' does not look right for native Linux use. Hence the option proposed at the end of the previous comment. Assigning to kernel team.

Such an option is unwanted in the GUI IMHO. It's too narrow/specialized niche. Windows needs fixing
