Subject: PROBLEM: linux 3.16 APIC and bhyve won't boot
Hello,
[1.] One line summary of the problem:
On Linux 3.16 a custom-built kernel with bhyve won't boot and will hang on the APIC timer calibration.
[2.] Full description of the problem/report:
I'm booting a 3.16 in bhyve (FreeBSD hypervisor) and according to my tests
lapic_cal_handler never gets called. This prevents the lapic_cal_loops
counter from being incremented and therefore the APIC calibration never
finishes. It is supposed to be called 25 times (APIC_CAL_LOOPS
constant). I added some apic_printk's to check for these infos (not a
best practice but I don't have access to a debugger in this specific
context).
[3.] Keywords (i.e., modules, networking, kernel):
kernel, apic
[4.] Kernel version (from /proc/version):
n/a (won't boot)

[7.7.] Other information that might be relevant to the problem
A stock Debian 3.2 kernel will boot. I don't have the possibility to build such a bloated kernel to
see what's missing. My goal is to identify what is the minimal set of functionalities needed to have
a kernel start up in a bhyve context. I have several other Linux VMs able to run on this hypervisor,
none with such a recent kernel.
Yours sincerely,
