Invalid opcode on resume from STR on Asus P4P800-VM

Invalid opcode on resume from STR on Asus P4P800-VM

[Ondrej Zary]

Hello,
I'm trying to debug oops on resume from suspend-to-RAM on Asus P4P800-VM
mainboard. It crashes with invalid opcode (see below). The kernel is 
2.6.32-trunk from Debian but the same problem is present with vanilla
kernels - both newer and older (but screen remains blank most of the time,
only keyboard LEDs blink indicating an oops).

What can cause this problem?

Not surpisingly, since mwait_usable() ignores the idle_nomwait flag.  
Maybe that's a bug and should be fixed -- I don't know.

It looks like idle=nomwait should be the workaround with the least 
impact at the moment..

That could be the answer.  Clearly this should be handled by the 
arch-specific boot/setup code.  I don't know enough about it, but other 
people do.

Thanks, it does not crash with "idle=halt" or "idle=poll". According to this:
http://siyobik.info/index.php?module=x86&id=215
the MWAIT instruction can be enabled/disabled in IA32_MISC_ENABLES MSR. Kernel 
probably should enable it at boot and also on resume.

I had exactly the same problem (on an HP computer with an Intel
chipset).  As far as anyone could figure out, it is caused by a bug in 
the BIOS.  It's not entirely clear that this is the complete answer, 
but nothing else turned up.  See

	http://bugzilla.kernel.org/show_bug.cgi?id=15385

for the complete record.  The best solution I could find was to boot
with "idle=halt" on the command line.  You might check to see if any 
BIOS updates are available.

Invalid opcode on resume from STR on Asus P4P800-VM

[Ondrej Zary]

Hello,
I'm trying to debug oops on resume from suspend-to-RAM on Asus P4P800-VM
mainboard. It crashes with invalid opcode (see below). The kernel is 
2.6.32-trunk from Debian but the same problem is present with vanilla
kernels - both newer and older (but screen remains blank most of the time,
only keyboard LEDs blink indicating an oops).

What can cause this problem?
