I've just upgraded my distribution so I tried qemu 1.0.1 which has the same behaviour as the former version.

Well, I've added some debug statements to the code:
void __init arch_init_ideal_nops(void)
{
switch (boot_cpu_data.x86_vendor) {
case X86_VENDOR_INTEL:
/*
* Due to a decoder implementation quirk, some
* specific Intel CPUs actually perform better with
* the "k8_nops" than with the SDM-recommended NOPs.
*/
if (boot_cpu_data.x86 == 6 &&
boot_cpu_data.x86_model >= 0x0f &&
boot_cpu_data.x86_model != 0x1c &&
boot_cpu_data.x86_model != 0x26 &&
boot_cpu_data.x86_model != 0x27 &&
boot_cpu_data.x86_model < 0x30) {
printk("NOPS: Option 1\n");
ideal_nops = k8_nops;
} else if (boot_cpu_has(X86_FEATURE_NOPL)) {
printk("NOPS: Option 2\n");
ideal_nops = p6_nops;
} else {
printk("NOPS: Option 3\n");
#ifdef CONFIG_X86_64
ideal_nops = k8_nops;
#else
ideal_nops = intel_nops;
#endif
}
break;
default:
#ifdef CONFIG_X86_64
ideal_nops = k8_nops;
#else
if (boot_cpu_has(X86_FEATURE_K8))
ideal_nops = k8_nops;
else if (boot_cpu_has(X86_FEATURE_K7))
ideal_nops = k7_nops;
else
ideal_nops = intel_nops;
#endif
}
}
This gives me Option 1 with "-cpu host" and Option 2 without.

dmesg is in the attachment (qemu ran without "-cpu" argument). If I add "-cpu host" I get this:

I've just upgraded my distribution so I tried qemu 1.0.1 which has the same behaviour as the former version.

Well, I've added some debug statements to the code:
void __init arch_init_ideal_nops(void)
{
switch (boot_cpu_data.x86_vendor) {
case X86_VENDOR_INTEL:
/*
* Due to a decoder implementation quirk, some
* specific Intel CPUs actually perform better with
* the "k8_nops" than with the SDM-recommended NOPs.
*/
if (boot_cpu_data.x86 == 6 &&
boot_cpu_data.x86_model >= 0x0f &&
boot_cpu_data.x86_model != 0x1c &&
boot_cpu_data.x86_model != 0x26 &&
boot_cpu_data.x86_model != 0x27 &&
boot_cpu_data.x86_model < 0x30) {
printk("NOPS: Option 1\n");
ideal_nops = k8_nops;
} else if (boot_cpu_has(X86_FEATURE_NOPL)) {
printk("NOPS: Option 2\n");
ideal_nops = p6_nops;
} else {
printk("NOPS: Option 3\n");
#ifdef CONFIG_X86_64
ideal_nops = k8_nops;
#else
ideal_nops = intel_nops;
#endif
}
break;
default:
#ifdef CONFIG_X86_64
ideal_nops = k8_nops;
#else
if (boot_cpu_has(X86_FEATURE_K8))
ideal_nops = k8_nops;
else if (boot_cpu_has(X86_FEATURE_K7))
ideal_nops = k7_nops;
else
ideal_nops = intel_nops;
#endif
}
}
This gives me Option 1 with "-cpu host" and Option 2 without.

dmesg is in the attachment (qemu ran without "-cpu" argument). If I add "-cpu host" I get this:

This looks like an emulation bug. The interesting thing is that your
both traces from the bugzilla point to generic_make_request_checks but
it could also be due to timing.
Decoding the instruction stream in the second trace in the bugzilla gives:

This looks like an emulation bug. The interesting thing is that your
both traces from the bugzilla point to generic_make_request_checks but
it could also be due to timing.
Decoding the instruction stream in the second trace in the bugzilla gives:

I can provide you with more different traces if it can help. But I thought that maybe it will be more useful for you to try it on your own. So I've prepared some minimal debian installation which you could download here (apx 163M bzipped):
http://fi.muni.cz/~xracek/debian.img.bz2
Password:
root/asdfgh
Here is my config for guest kernel:
http://fi.muni.cz/~xracek/config
I use
qemu-kvm -m 1500 -hda debian.img -kernel linux/arch/x86/boot/bzImage -append "root=/dev/sda1"
After logging in just run "sh runtest.sh". This leads to crash in my case (host: Intel Core i5-2540M, kernel 3.5.2-1.fc17.x86_64, qemu 1.0.1).

I can provide you with more different traces if it can help. But I thought that maybe it will be more useful for you to try it on your own. So I've prepared some minimal debian installation which you could download here (apx 163M bzipped):
http://fi.muni.cz/~xracek/debian.img.bz2
Password:
root/asdfgh
Here is my config for guest kernel:
http://fi.muni.cz/~xracek/config
I use
qemu-kvm -m 1500 -hda debian.img -kernel linux/arch/x86/boot/bzImage -append "root=/dev/sda1"
After logging in just run "sh runtest.sh". This leads to crash in my case (host: Intel Core i5-2540M, kernel 3.5.2-1.fc17.x86_64, qemu 1.0.1).

Um. I'd expect the image to be self-contained, no external kernel.
I wanted to do a quick test to see if it fails on my machine too,
d/loaded debian.img.bz2 but there's no kernel. So.. no quick test
for you ;)

With all the above, this "runtest.sh" is informationally equal to
your disk image.

Well, the point was to use the latest sources instead of some image which can be obsolete tomorrow. However I created a new image with today's kernel which you can use:
http://fi.muni.cz/~xracek/debian2.img.bz2
Other things are the same.
The runtest.sh sets environment for xfstests and runs test 285 which I wrote and and which should test if FS sends discard requests only on free sectors:
285:
1. Create loop device and FS on it.
2. Populate it with some garbage.
3. Get free sectors from FS.
4. Run fstrim and look for discard requests via blk tracer.
5. Compare free sectors to discard requests.
The test itself can have some issues but I'm pretty sure it shouldn't crash the system. ;-)

Tom

It's obvious that it should. You're running a non-modular kernel, and those nops are discarded (probably a leftover from the days patching was a boot-only activity), so the kernel patched garbage over its own code.

Probably a leftover from the early days of self-patching, p6nops are
marked __initconst_or_module, which causes them to be discarded in a
non-modular kernel. If something later triggers patching, it will
overwrite kernel code with garbage.

x86/alternatives: Fix p6 nops on non-modular kernels
Probably a leftover from the early days of self-patching, p6nops
are marked __initconst_or_module, which causes them to be
discarded in a non-modular kernel. If something later triggers
patching, it will overwrite kernel code with garbage.
