Hi John, fdc seems to cause panic on Hyper-V: https://people.freebsd.org/~sephe/fdc_panic.png I then commented out device fdc, and I fixed one panic on Hyper-V here: https://reviews.freebsd.org/D8656 After fdc is disabled and hyperv/storvsc is fixed, it seems to boot fine, except a long delay (28~30seconds) here: .... Timecounters tick every 1.000 msec ----- 28 ~ 30 seconds delay ----- vlan: initialized, using hash tables with chaining .... I have the bootverbose dmesg here: https://people.freebsd.org/~sephe/dmesg_earlyap.txt I booted 10 times, only one boot does not suffer this 30 seconds delay. It sounds like some races to me. Any hints? Thanks, sephe On Sat, Nov 26, 2016 at 2:20 AM, John Baldwin <jhb@freebsd.org> wrote: > I plan to enable EARLY_AP_STARTUP on x86 in a week on HEAD.
