It dies so hard that makes NMI watchdog useless. It's not a new bug, and we are close to root causing it. In function acpi_ex_system_io_space_handler(): 301 case ACPI_WRITE: 302 303 status = acpi_os_write_port((acpi_io_address) address, 304 (u32) * value, bit_width); 305 break; The notebook stalls immediately after line 303, which is triggering an SMI, and invoking SMM code to interact with system firmware. Lin Ming and Zhao Yakui helped locating this line. Zhang Rui collected a lot detailed info and is working on this issue.

I don't know how you provoked this failure. The ACPI interpreter should always be run with interrupts enabled. If it isn't then that is a (different) bug.

Hi, Len The issue on Fengguang's laptop is different with that on the box of T61. On Fengguang's laptop after evaluating one ACPI object(GPE _L18object), the irq is disabled mystically. After some investigations we find that it is caused by SMI(The SMI will be triggered while evaluating the ACPI object. And this issue is also related with Video). If the boot option of "noapic" is added on the box of bug12252, the irq_router_resume will be called, in which the _CRS/_SRS object will be evaluated. But unfortunately the irq is disabled when irq_router_resume is called.

I hadn't realized you root-caused that failure. This is good to know, but the fact that SMM can leave interrupts disabled is frightening. If the BIOS SMM on that box disables interrupts when random AML is run, then it is going to run into all kinds of other problems in addition to this one... Hopefully the BIOS bugs is fixed by a BIOS update... > If the boot option of "noapic" is added on the box of bug12252, the > irq_router_resume will be called, in which the _CRS/_SRS object will be > evaluated.

I forced the T61 to run into this problem by forcing it to use PIC mode and suspending -- for it doesn't use the links in IOAPIC mode. Many other systems do use the links in default mode, however, so I'm surprised that we had not heard more about this failure. Now that I search for acpi_ps_complete_op() on kerneloops.org, I see that just a few people have run into it. thanks, -- Len Brown, Intel Open Source Technology Center> ^ permalink raw reply [flat|nested] 11+ messages in thread

If it had been implemented, this insanity would not be possible. Every time a BIOS writer uses SMM, they should be rewarded by having a digit severed. This is a very simple proposal, very easy to understand. Further, with "10-strikes and you're out", it comprehends that there may be some BIOS writerse that take a while to catch on... However, when they run out of fingers I'd draw the line and insist that they find a new line of work. -Len ^ permalink raw reply [flat|nested] 11+ messages in thread

I'm not sure I understand your scheme. But what if the first 10-strikes already makes system unstable? OpRegion seeks to replace SMI, however it may take time. ^ permalink raw reply [flat|nested] 11+ messages in thread

This machine should likely be added to that list. Might be that Linux and the BIOS stomping on this memory in combination is related to some of the other problems seen as well.. These BIOS authors really need to be beaten with a stick though.. they can't be using this memory without properly marking it as reserved in E820 tables. ^ permalink raw reply [flat|nested] 11+ messages in thread
