Dendrobatus AzureusThe last time I experienced a kernel panic while just working, was so long ago {decade+} I don't even rememberI got multiple kernel panics todayAchievement!The question is how did it occur.I was tuning up certain parameters in the UEFI system of a machine. One of the parameters was a video memory window, that I put up to the max, since the machine has 40 gigs of RAM. It turns out that when you put that all the way up, the UEFI configures the machine in such a way that a POSIX kernel does not know how to work with that window, gets nervous, panics barfs, and then screams like a banshee, running away in Horror, Terror then Jumping into a black holeI found out fast what it was because I change parameters one by one then test them out.It's also turns out that there is a bug, a serious bug, in the EFI system of that machine, causing the kernel to barf, run, scream like a banshee and jump into the black hole.I am however not going to patch that bug since patching EFI systems is so risky that you have to have a significant amount of redundant power delivery before you can even think about doing such a mission critical task.**See noteThe machine has just come in.Stumbling upon bugs is something I doI'm a high level beta tester.Leave it alone don't use that parameter all the way up to that level, and everything will be fine. That is what I told myself and has been decided to the final.Getting my redundant Alternating Current delivery to the proper level will take about 1200 EUR, Cash that I do not have in spare at this moment.I will need Power Delivery Units with built-in surge protection, which I will need to connect to at least Four Uninterruptible Powersupply Systems, running on deep cycle batteries.**Note an update is available for the UEFI system of this machine, slamming that bug down.The manufacturer of the machine has warned specifically that you only need to take that specific patched EFI, if you have that problem. The other newer patches should be left alone if you don't have any problems with the other things.<a href="https://polymaths.social/tags/kernel" class="mention hashtag" rel="nofollow noopener" target="_blank">#Kernel</a> <a href="https://polymaths.social/tags/panic" class="mention hashtag" rel="nofollow noopener" target="_blank">#panic</a> <a href="https://polymaths.social/tags/debugging" class="mention hashtag" rel="nofollow noopener" target="_blank">#debugging</a> <a href="https://polymaths.social/tags/post" class="mention hashtag" rel="nofollow noopener" target="_blank">#POST</a> <a href="https://polymaths.social/tags/efi" class="mention hashtag" rel="nofollow noopener" target="_blank">#EFI</a> <a href="https://polymaths.social/tags/refi" class="mention hashtag" rel="nofollow noopener" target="_blank">#rEFI</a> <a href="https://polymaths.social/tags/programming" class="mention hashtag" rel="nofollow noopener" target="_blank">#programming</a> <a href="https://polymaths.social/tags/posix" class="mention hashtag" rel="nofollow noopener" target="_blank">#POSIX</a>

Saemon ZixelUEFI оказалась не такой уж и сложной технологией.Оказывается, можно просто создать раздел FAT32 с типом ef, сделать его активным, создать там папку EFI, а в ней BOOT. И положить туда grubx64.efi переименовав его в bootx64.efi. И при перезагрузке прошивка EFI материнской платы сама найдёт этот раздел, залезет в папку EFI/BOOT и загрузит и запустит bootx64.efi. И появится командная строка GRUB2.Если подложить в правильное место grub.cfg, то появится меню, а не командная строка.Поскольку я использовал для экспериментов GRUB из ubuntu, то в нём был захардкожен путь /EFI/ubuntu. Соответственно, туда и пришлось класть grub.cfg и grubenv (для удобства).Но это при условии, если в NVRAM переменные BOOT001, BOOT002 и т.д. отсутствуют или ведут к несуществующим или поломанным загрузчикам. UEFI в первую очередь пытается загрузить файлы загрузчики из этих переменных.Можно ещё распаковать в EFI раздел rEFInd, который может загружать разные операционные системы в режиме EFI. А поскольку он основывается на GRUB2, тоже умеет напрямую грузить ядро linux.<a href="https://lor.sh/tags/uefi" class="mention hashtag" rel="nofollow noopener" target="_blank">#uefi</a> <a href="https://lor.sh/tags/efi" class="mention hashtag" rel="nofollow noopener" target="_blank">#efi</a> <a href="https://lor.sh/tags/grub2" class="mention hashtag" rel="nofollow noopener" target="_blank">#grub2</a> <a href="https://lor.sh/tags/refind" class="mention hashtag" rel="nofollow noopener" target="_blank">#refind</a> <a href="https://lor.sh/tags/devops" class="mention hashtag" rel="nofollow noopener" target="_blank">#devops</a> <a href="https://lor.sh/tags/linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#linux</a>
