--- Comment #29 from Wei Hu <w...@microsoft.com> --- We have narrowed down the problem area to serial console output in FreeBSD and Azure COM emulator. Seems these two don't work very well at the early boot time. Maybe some synchronizing event was missing which causes the hang. The interesting part is, if the boot passes certain stage, the serial console works 100% fine. So, the temporary workaround is to suppress all printf's from the beginning of boot up until: SYSINIT(cpu, SI_SUB_CPU, SI_ORDER_FIRST, cpu_startup, NULL); We are working on checking the state of COM emulator in Azure to understand the cause. -- You are receiving this mail because: You are the assignee for the bug.
