Bare metal Freeze/Crash at Native.Sti() call in ThreadPool.Initialize

[ghost]

Running on an I7 6700K bare metal, OS freezes/crashes without any output at Native.Sti() call in ThreadPool.Initialize()

MOOS/Kernel/Misc/Threading.cs

Line 145 in 10737de

Native.Sti();

Same ISO works fine in QEMU, Can try to extract more information with WriteLines prior if it'd be at all helpful 😅

Console.WriteLine before and after the call in question, output looks like:

Happens with GC & GUI disabled, or enabled. Both work in VM. APIC build var can't be disabled without code changes; Timer and presumably other stuff uses it without compiler ifs.

Same issue on i7 Thinkpad x230

Also confirmed that everything but Threadpool (and SMP) works; can initialize everything else, and at least read/write from/to console in a loop.

Does it just freeze or get panic information?

Oh @iBeizsley

Try not initialize sata controller

[nifanfa]

MOOS/Kernel/Misc/EntryPoint.cs

Line 79 in 10737de

SATA.Initialize();

[nifanfa]

i remember sata controller have some problems

[ghost]

Just freezes, no panic. Disabling SATA didn't work, went ahead and tried with Keyboard, Serial, PS2, VMware tools, SMBIOS, PCI, IDE and SATA all disabled, same result:

Just for clarity, writeline before the Native.Sti being the last thing here, there's a second writeline immediately after, before Schedule_Next, not getting hit.

try not initialize threadpool and smp and see if it works

[nifanfa]

i'll check it as soon as possible

[nifanfa]

just make sure it is a problem of threadpool

[nifanfa]

[nifanfa]

yeah i got the same problem

[nifanfa]

so the problem looks like the trampoline address

[nifanfa]

@iBeizsley

[nifanfa]

no the problem is ThreadPool for sure

I just reverted the newest changes. you can use this one

[nifanfa]

it works fine on real hardware

[nifanfa]

[nifanfa]

The problem might be with native aot itself. We can't make Corlib a lib instead of shared project

[nifanfa]

So the problem is solved

[nifanfa]

i just renamed stable to main btw

[nifanfa]

let me know if it works now

[nifanfa]

I found that the real problem is that ILCompiler is not stable
