I'd like to know if building the module by hand makes the crashes disappear. (Obviously, this is relevant only if you didn't do that from the start when testing drm-515-kmod.) > Is there any whitepaper or so, detailing this, perhaps while reverse-engi= neering the code base? You can find plenty of information on the web about RCU, such as: https://www.kernel.org/doc/html/latest/RCU/whatisRCU.html if that is your question? We have a couple of mechanisms in the FreeBSD kernel doing similar things. > We have to thank all volunteers here to come close that quality for an OS= you can get for free and running realiably on HW for just $300 (like mine). Of course. And also paid people catering to other users' needs. --=20 You are receiving this mail because: You are the assignee for the bug.=
