https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D259878 Bug ID: 259878 Summary: [hyper-v] Kernel hangs at boot after printing Hyper-V features Product: Base System Version: 13.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: sneakywumpus@gmail.com After commit a2ca269b3810 ("hyperv: Register hyperv_timecounter later during boot") my Gen2 Hyper-V VM with 6 CPUs (on Windows 11 Pro 22000.318) hangs at boot after printing the Hyper-V features but before printing the CPU-ID features and consumes 100% single core CPU. After looking at the commit comments and code I changed SYSINIT(hyperv_tc_init, SI_SUB_DRIVERS, SI_ORDER_FIRST, hyperv_tc_init, NUL= L); to SYSINIT(hyperv_tc_init, SI_SUB_LOCK + 1, SI_ORDER_FIRST, hyperv_tc_init, NU= LL); in sys/dev/hyperv/vmbus/hyperv.c . I'm really no kernel programmer so I don't know if this is the right thing = to do, but this change fixed the problem for me. --=20 You are receiving this mail because: You are the assignee for the bug.=
