So I configured a kernel with the following option: options KTR_ENTRIES="(1024UL*1024)" then booted the kernel and did $ sysctl debug.ktr.clear=1 and got an insta-reboot. No panic, nothing, just a reset. I suspect that the huge static buffer resulting from the above option could be a cause. But I would like to understand the details, if possible. Also, perhaps ktr could be a little bit more sophisticated with its buffer than just using a static array. -- Andriy Gapon
