--- Comment #2 from François Gouget fgouget@codeweavers.com --- Based on the WineTest results: * It only fails on real hardware and the TestBot only runs it on QEMU VMs. * It fails the same way whether the machine is running Windows 8, 8.1 or 10. * It fails the same way for 32 and 64 bit tests. * In every failing case the the SpinCount value is 33556432 or 0x020007d0. Does this value mean anything?
Maybe it's a CPU topology issue: all VMs emulate a dual single-core processor systems while the failures happen on single multi-core processor machines.
