running the AML interpreter in interrupt context would be a no-no. I thought we had deferred the notify handlers so that they wouldn't run in interrupt context, but maybe there is a case here where that does not happen.
Yes, I tracked though the kernel acpi code as much as I could, and found that I was making acpi calls that did kmalloc() with the 'wrong' arg. in a context that didn't allow it (where /proc reads would). Unfortunately, the solutions I tried (diff. ways of deferral using notify handlers) still failed, or at least stuffed it on boot (which is what my current code-base does). The last code I traced was the bit that looked up the full ACPI ref. from a local ref., and that does a malloc, so I did the lookup at module init and stored that full string to bypass the lookup malloc later, but then it just goes wrong a bit later :-( -- [neil@fnx ~]# rm -f .signature [neil@fnx ~]# ls -l .signature ls: .signature: No such file or directory [neil@fnx ~]# exit - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
