Hi,
I have a problem with random oopses on boot,
every 1 out of 5 times I boot linux freezes.
I was not able to obtain a call trace, however it happens around 10-15
seconds after boot. I can hear that the tg3 driver is initialised.
In this thread, they have the same problem:
https://bugzilla.novell.com/show_bug.cgi?id=647029
Applying the patch from the thread, makes the problem occurring less
often and dmesg shows acpi-button loads for me on hid PNP0C0C and
LNXPWRBN.
Maybe commit e2fb9754d27513918a4936e8cbaad50ff56cfd3d
ACPI: button: remove unnecessary null pointer checks
has unmasked an underlying problem?

The oopses from the bugzilla are not the sort I would expect from a null pointer dereference, but since it's fairly reproducible for you, it might be worth reverting e2fb9754d27 to see whether it makes any difference. Does Rich's script from https://bugzilla.novell.com/show_bug.cgi?id=647029#c30 help you reproduce the problem? Bjorn ^ permalink raw reply [flat|nested] 14+ messages in thread

I was not able to revert it. But it would only mask the problem anyway... I have now reverted bf04a77227db76f163bc2355ef4e176794987be2 ACPI: button: cache hid/name/class pointers and build acpi_button as a module but this makes no difference. > Does Rich's script from https://bugzilla.novell.com/show_bug.cgi?id=647029#c30 > help you reproduce the problem? No, it only crashes on boot (without the printk patch). If it happens the machine is completely dead, SysRq does not work. However it is definitely the acpi_button module, because removing it also fixes this. -Tobias ^ permalink raw reply [flat|nested] 14+ messages in thread

Right, but now the granularity is "remove the acpi_button driver completely." If we can identify a specific statement inside acpi_button that makes a difference, that might help. > I have now reverted bf04a77227db76f163bc2355ef4e176794987be2 > ACPI: button: cache hid/name/class pointers and build acpi_button > as a module but this makes no difference. > > > Does Rich's script from https://bugzilla.novell.com/show_bug.cgi?id=647029#c30 > > help you reproduce the problem? > > No, it only crashes on boot (without the printk patch). > If it happens the machine is completely dead, SysRq does not work. > > However it is definitely the acpi_button module, because removing it > also fixes this. If it crashes on boot (not when loading an acpi_button module), you must be building acpi_button into the static kernel. The acpi_button driver has a fairly complicated add() method. In the absence of a better idea, I might just comment out blocks of it and try to isolate the problem. For example, take out all the input stuff, take out the wakeup GPE stuff, take out the type/name setup, etc. Bjorn ^ permalink raw reply [flat|nested] 14+ messages in thread

It does crash on boot either if built-in to the kernel or as a module, However it does not crash if the module is loaded/unloaded after the machine has booted. > The acpi_button driver has a fairly complicated add() method. > In the absence of a better idea, I might just comment out blocks > of it and try to isolate the problem.

Adding some printk's to fix it seems to be insane. -Tobias ^ permalink raw reply [flat|nested] 14+ messages in thread

Agreed, adding printk's is absolutely not any kind of fix. I think it's more likely to be some sort of memory corruption or race than a compiler problem. I assume there is some old kernel that works fine, even when compiled with the same compiler. In addition to the isolation ideas I suggested above, you might boot with "maxcpus=1" and turn on all the Kconfig memory debug switches.

Aren't there some memory corruption checkers which can additionally be enabled? CONFIG_DEBUG_SLAB Say Y here to have the kernel do limited verification on memory allocation as well as poisoning memory on free to catch use of freed memory. This can make kmalloc/kfree-intensive workloads much slower. CONFIG_DEBUG_VM Enable this to turn on extended checks in the virtual-memory system that may impact performance. CONFIG_DEBUG_LIST Enable this to turn on extended checks in the linked-list walking routines. CONFIG_DEBUG_PAGEALLOC Unmap pages from the kernel linear mapping after free_pages(). This results in a large slowdown, but helps to find certain types of memory corruption. Did I oversee one? Not sure which is best, it should not hurt to turn on all (if possible) for a test.

And when it crashes on boot, there is never a call trace to see. I hope Rich is still interested in a solution as I am. The bad thing is that the latest working version I had been running on that machine was ancient 2.6.23. So this problem is a regression, which I would have noticed earlier, if I had updated that machine more often. It is not an hardware problem, I have edac enabled and I don't see any errors. The only strange thing I get related to memory is an mtrr entry of 64GB (I only have 6GB). -Tobias ^ permalink raw reply [flat|nested] 14+ messages in thread

I reproduced this on later kernels, 2.6.36 (I think). I've been working on a project that's almost finished, then I plan on going back to tracking down this issue.
