Hello everyone,

So this is a windows 10 VM with random freezes. Only stopping and startingt fixes it. This started to happen in the last 2 or 3 weeks. I have changed cpu type, raised memory and cores. Even changed the display options. Same result. Once in a while it also shows a split lock.

Code:
2026-03-22T15:22:02.495953+00:00 prox kernel: x86/split lock detection: #AC: CPU 0/KVM/263079 took a split_lock trap at address: 0xfffff8012fe1e643
2026-03-22T22:27:31.680714+00:00 prox kernel: perf: interrupt took too long (3142 > 3136), lowering kernel.perf_event_max_sample_rate to 63000
2026-03-23T07:13:24.132959+00:00 prox kernel: x86/split lock detection: #AC: CPU 1/KVM/263080 took a split_lock trap at address: 0x20c03394aff

It had the lastest version of virtio drivers, but downgraded to 0.1.271 as recommended here in proxmox's support pages. Nothing changed.
Also, no "fancy" software running there.
