As Peters mail does not seem to exists any more, I'll ask here (LKML and LHV), if all right: Is there any news about this bug on Hyper-V hosts? If this is actually a Hyper-V (host) bug, was it ever addressed and fixed? I encounter this bug when using Windows 11 Enterprise (25H2) host and Oracle Linux 8 and 9 as guests. They use an older kernel, so I can't use this parameter to fix it. Windows guests do not seem to be affected by it, in my experience. Feel free to reply off list, as it is not really on topic.
