Created attachment 189861 [details] dmesg of vanilla/untouched 4.2.3 kernel
Confirm it's not grsec specifics, it's also happened on vanilla/untouched 4.2.3 kernel!. Attached above the dmesg for the vanilla one.
Looks like a module order issue. Rui, do you have any progress in converting acpi_ipmi driver? I also found something on the patchwork: https://patchwork.kernel.org/patch/6579001/ Can this issue be solved the above metioned fix? Thanks and best regards -Lv
No, I didn't do anything about converting acpi_ipmi driver.
Zheng, thanks for the pointer to the patch, but i am still experiencing the issue.

This seems to be a dependency issue to me. In your case, the acpi power meter device access an IPMI operation region, and the driver is probed before the IPMI address space handler being registered. To confirm this, please check if the problem can be reproduced when the kernel is built with 1. CONFIG_IPMI_SI=y 2. CONFIG_ACPI_IPMI=y 3. CONFIG_SENSORS_ACPI_POWER=m
